That was my initial reaction as well, but I failed to notice the sizeof
which prevents the new warning.

I can rebase. What's your preferred target? media-next?

Indeed. Before the 5 commits below, a missing dependency on HAS_DMA
would cause the build to fail for NO_DMA platforms.
f29ab49b5388b2f8 dma-mapping: Convert NO_DMA get_dma_ops() into a real dummy

It should not cause build issues, but it would enable lots of drivers that
need DMA platform support on platforms where they wouldn't work, making the
life of distro configurators harder.
That's why my series removes HAS_DMA only for symbols that have a platform
dependency.
Thanks!

[PATCH 01/30] staging: wilc1000: added complete() call for error scenario in handle_key()
During memory allocation failure in handle_key() the complete() was not
called for comp_test_key_block event. So now added the code to call
complete() for event during error scenario.

[PATCH 27/30] staging: wilc1000: remove 'flag' argument from wilc_mac_indicate()
Remove 'flag' function parameter in wilc_mac_indicate() as only one
condition was handled using that parameter. Also removed unnecessary
call to wilc_mac_indicate() as no operation was performed in that
function call.
After above changes below macro are not required.
This changes also helped in resolving the line over 80 chars issue
found by checkatpch.pl script.

Re: A few questions about warnings in the ion driver
On 05/06/2018 06:43 PM, Nathan Chancellor wrote:
Hi everyone,
I compiled the ion driver with W=1 where I encountered the two following
warnings and I had a couple of questions about solving them.
1.
drivers/staging/android/ion/ion.c: In function ‘ion_dma_buf_begin_cpu_access’:
drivers/staging/android/ion/ion.c:316:8: warning: variable ‘vaddr’ set but not
used [-Wunused-but-set-variable]
which concerns the following function:
static int ion_dma_buf_begin_cpu_access(struct dma_buf *dmabuf,
enum dma_data_direction direction)
{
struct ion_buffer *buffer = dmabuf->priv;
void *vaddr;
struct ion_dma_buf_attachment *a;
/*
* TODO: Move this elsewhere because we don't always need a vaddr
*/
if (buffer->heap->ops->map_kernel) {
mutex_lock(&buffer->lock);
vaddr = ion_buffer_kmap_get(buffer);
mutex_unlock(&buffer->lock);
}
mutex_lock(&buffer->lock);
list_for_each_entry(a, &buffer->attachments, list) {
dma_sync_sg_for_cpu(a->dev, a->table->sgl, a->table->nents,
direction);
}
mutex_unlock(&buffer->lock);
return 0;
}
Can vaddr be removed and just have ion_buffer_kmap_get remain, since it is
never used again in the function?
I think a better solution is to check the return value of vaddr
and error out if it fails.
2.
drivers/staging/android/ion/ion_carveout_heap.c:106:18: warning: no previous
prototype for ‘ion_carveout_heap_create’ [-Wmissing-prototypes]
drivers/staging/android/ion/ion_chunk_heap.c:111:18: warning: no previous
prototype for ‘ion_chunk_heap_create’ [-Wmissing-prototypes]
It appears neither of these functions are used since commit 2f87f50b2340
("staging: android: ion: Rework heap registration/enumeration"). Ultimately,
removing the whole file fixes this warning; is there still a need to rework
them or can they be removed?
I'd still like to delete it. I haven't seen anyone come out to re-work it.
That said, I think my preference is still to keep it for now until
we do another round of updates.
Thanks for looking at these.
Laura

Something like this? I was unsure if -ENOMEM or -EINVAL was a better
error return code in this context.

Understood, I figured it probably isn't wise to remove stuff in the
middle of a release cycle but hey, never know. I will leave it alone
for now.

[PATCH v3 00/14] media: staging/imx7: add i.MX7 media driver
Hi, This series introduces the Media driver to work with the i.MX7 SoC. it uses the already existing imx media core drivers but since the i.MX7, contrary to i.MX5/6, do not have an IPU and because of that some changes in the imx media core are made along this series to make it support that case. This patches adds CSI and MIPI-CSI2 drivers for i.MX7, along with several configurations changes for this to work as a capture subsystem. Some bugs are also fixed along the line. And necessary documentation. For a more detailed view of the capture paths, pads links in the i.MX7 please take a look at the documentation in PATCH 14. The system used to test and develop this was the Warp7 board with an OV2680 sensor, which output format is 10-bit bayer. So, only MIPI interface was tested, a scenario with an parallel input would nice to have. *Important note*, this code depends on Steve Longerbeam series [0]: [PATCH v3 00/13] media: imx: Switch to subdev notifiers which the merging status is not clear to me, but the changes in there make senses to this series Bellow goes an example of the output of the pads and links and the output of v4l2-compliance testing. The v4l-utils version used is: v4l2-compliance SHA : 47d43b130dc6e9e0edc900759fb37649208371e4 from Apr 4th. The Media Driver fail some tests but this failures are coming from code out of scope of this series (video-mux, imx-capture), and some from the sensor OV2680 but that I think not related with the sensor driver but with the testing and core. The csi and mipi-csi entities pass all compliance tests.

+Video Media Controller node
+---
+
+This is the media controller node for video capture support.
It is a
+virtual device that lists the camera serial interface nodes
that the
+media device will control.
+
+Required properties:
+- compatible : "fsl,imx7-capture-subsystem";
+- ports : Should contain a list of phandles pointing to
camera
+ sensor interface port of CSI
+
+example:
+
+capture-subsystem {
+ compatible = "fsl,imx7-capture-subsystem";
+ ports = <&csi>;
Why do you need this node? Just have the driver match on the CSI
node.
This is for the parsing of the nodes done in imx media core, see
also
the imx.txt file.
+};
+
+
+mipi_csi2 node
+--
+
+This is the device node for the MIPI CSI-2 receiver core in
i.MX7 SoC. It is
+compatible with previous version of Samsung D-phy.
Compatible with Samsung?
+
+Required properties:
+
+- compatible: "fsl,imx7-mipi-csi2";
+- reg : base address and length of the register set
for the device;
+- interrupts: should contain MIPI CSIS interrupt;
+- clocks: list of clock specifiers, see
+
Documentation/devicetree/bindings/clock/clock-bindings.txt for
details;
+- clock-names : must contain "mipi" and "phy" entries,
matching entries in the
+ clock property;
+- power-domains : a phandle to the power domain, see
+
Documentation/devicetree/bindings/power/power_domain.txt for
details.
+- reset-names : should include following entry "mrst";
+- resets: a list of phandle, should contain reset
entry of
+ reset-names;
+- phy-supply: from the generic phy bindings, a phandle to
a regulator that
+ provides power to VBUS;
VBUS? Copy-n-paste from USB something?
yeah, c-n-p error.
+- bus-width : maximum number of data lanes supported (SoC
specific);
Don't we have a standard lanes property for CSI (or DSI)?
bus-width is
for parallel buses and goes in endpoint nodes. (But maybe it got
used
here too).
+
+Optional properties:
+
+- clock-frequency : The IP's main (system bus) clock frequency
in Hz, default
+ value when this property is not specified is
166 MHz;
+
+port node
+-
+
+- reg : (required) can take the values 0 or 1,
where 0 is the
+ related sink port and port 1 should be
the source one;
+
+endpoint node
+-
+
+- data-lanes: (required) an array specifying active
physical MIPI-CSI2
+ data input lanes and their mapping to logical
lanes; the
+ array's content is unused, only its length is
meaningful;
Ah yes, like this. :) So why do you need bus-width too?
To guarantee that the active lanes are not bigger that the ones
supported in the specific SoC. So, the bus-width defines the lanes
supported and this the active ones.
+
+- csis-hs-settle : (optional) differential receiver (HS-RX)
settle time;
units?
+- csis-clk-settle : (optional) D-PHY control register;
+- csis-wclk : CSI-2 wrapper clock selection. If this
property is present
+ external clock from CMU will be used, or the bus
clock if
+ if it's not specified.
boolean?
I dropped this in v3.
These 3 need vendor properties.
Sure, added in v3
+
+example:
+
+ mipi_csi: mipi-csi@3075 {
+clock-frequency = <16600>;

+#address-cells = <1>;

[PATCH v3 04/14] clk: imx7d: reset parent for mipi csi root
To guarantee that we do not get Overflow in image FIFO the outer bandwidth has to be faster than inputer bandwidth. For that it must be possible to set a faster frequency clock.

On second glance, I did not realize most of these functions involve
pointer semantics. Please do not apply this. I can send a v2 series if
necessary although every other patch is fine.

[PATCHv2] staging: speakup: Add pause command used on switching to graphical mode
For software speech syntheses to be able to manage concurrent audio card
access, they need to know when speakup stops emitting text to be spoken
because the console has switched to graphical mode. This introduces a
PAUSE command to do so.

[PATCH char-misc 0/2] Drivers: hv: vmbus: Remove x86-isms in arch independent code

The first patch moves x86-specific code out of the Hyper-V architecture independent drivers and into the arch/x86 directory.

[PATCH char-misc 2/2] Drivers: hv: vmbus: Make TLFS #define names architecture neutral
From: Michael Kelley
The Hyper-V feature and hint flags in hyperv-tlfs.h are all defined
with the string "X64" in the name. Some of these flags are indeed
x86/x64 specific, but others are not. For the ones that are used
in architecture independent Hyper-V driver code, or will be used in
the upcoming support for Hyper-V for ARM64, this patch removes the
"X64" from the name.
This patch changes the flags that are currently known to be
used on multiple architectures. Hyper-V for ARM64 is still a
work-in-progress and the Top Level Functional Spec (TLFS) has not
been separated into x86/x64 and ARM64 areas. So additional flags
may need to be updated later.
This patch only changes symbol names. There are no functional
changes.

[PATCH char-misc 1/2] Drivers: hv: vmbus: Remove x86 MSR refs in arch independent code
From: Michael Kelley
In architecture independent code for manipulating Hyper-V synthetic timers
and synthetic interrupts, pass in an ordinal number identifying the timer
or interrupt, rather than an actual MSR register address. Then in
x86/x64 specific code, map the ordinal number to the appropriate MSR.
This change facilitates the introduction of an ARM64 version of Hyper-V,
which uses the same synthetic timers and interrupts, but a different
mechanism for accessing them.

Thanks - your solution is probably better than the two I suggested!

[PATCH v3] staging: lustre: o2iblnd: Enable Multiple OPA Endpoints between Nodes
OPA driver optimizations are based on the MPI model where it is
expected to have multiple endpoints between two given nodes. To
enable this optimization for Lustre, we need to make it possible,
via an LND-specific tuneable, to create multiple endpoints and to
balance the traffic over them.
Both sides of a connection must have this patch for it to work.
Only the active side of the connection (usually the client)
needs to have the new tuneable set > 1.
