Also check the length of known notifications before accessing anything

There's not much we can get here, is the device working?  Is it not?
What happens?  Reading a single string isn't a big deal, are there any
other kernel logs?

thanks,

[PATCH RFC 0/7] phylib MMD accessor cleanups

2017-03-19 Thread Russell King - ARM Linux 
Hi,

This series cleans up the phylib MMD accessors.  We have two accessors
at present, phy_(read|write)_mmd() and phy_(read|write)_mmd_indirect()

The _indirect methods access the MMD registers via a clause 22 phy,
whereas the non-_indirect methods acess via clause 45 accesses.

Current PHY-independent parts of phylib (such as EEE) access the MMD
registers via the _indirect methods, which is no good if you have a
clause 45 PHY that doesn't respond to clause 22 accesses.

In order to make these features available, we need to rework these
accessors such that they can access the MMD registers using a method
dependent on the clause that the PHY conforms with.

This series of patches does exactly that - we merge the functionality
of the indirect accesses into the clause 45 accessors, and use these
exclusively to access MMD registers.  Internally, the new clause
independent MMD accessors indirect via the PHY drivers read_mmd/write_mmd
methods if present, otherwise fall back to using clause 45 accesses if
the PHY is a clause 45 phy, or clause 22 indirect accesses if the PHY
is clause 22.

Note: confusingly, phy_read_mmd_indirect() vs phy_read_mmd() switches
the order of prtad and devad, which means that converting between the
two is not a simple matter of just replacing the function name.  Same
applies for the write methods.

[PATCH RFC 3/7] net: lan78xx: update for phy_(read|write)_mmd_indirect() removal

2017-03-19 Thread Russell King 
lan78xx appears to use phylib in a rather weird way, accessing the PHY
partly through phylib, and partly by makign direct accesses to it,
including to the Clause 45 registers.  As the indirect MMD accessors are
going away, update this driver to use the plain phy_(read|write)_mmd()
accessors instead.

Hi Russell

This all looks good, apart from the one typo i spotted.

[PATCH v6 00/15] Replace PCI pool by DMA pool API

2017-03-19 Thread Romain Perier 
The current PCI pool API are simple macro functions direct expanded to
the appropriate dma pool functions. The prototypes are almost the same
and semantically, they are very similar. I propose to use the DMA pool
API directly and get rid of the old API.

This set of patches, replaces the old API by the dma pool API
and remove the defines.

Changes in v6:
- Fixed an issue reported by kbuild test robot about changes in DAC960
- Removed patches 15/19,16/19,17/19,18/19. They have been merged by Greg
- Added Acked-by Tags

Changes in v5:
- Re-worded the cover letter (remove sentence about checkpatch.pl)
- Rebased series onto next-20170308
- Fix typos in commit message
- Added Acked-by Tags

Changes in v4:
- Rebased series onto next-20170301
- Removed patch 20/20: checks done by checkpath.pl, no longer required.
  Thanks to Peter and Joe for their feedbacks.
- Added Reviewed-by tags

Changes in v3:
- Rebased series onto next-20170224
- Fix checkpath.pl reports for patch 11/20 and patch 12/20
- Remove prefix RFC
Changes in v2:
- Introduced patch 18/20
- Fixed cosmetic changes: spaces before brace, live over 80 characters
- Removed some of the check for NULL pointers before calling dma_pool_destroy
- Improved the regexp in checkpatch for pci_pool, thanks to Joe Perches
- Added Tested-by and Acked-by tags

2017-03-19 Thread Romain Perier 
The PCI pool API is deprecated. This commit replaces the PCI pool old
API by the appropriate function with the DMA pool API.

[PATCH v6 15/15] PCI: Remove PCI pool macro functions

2017-03-19 Thread Romain Perier 
Now that all the drivers use dma pool API, we can remove the macro
functions for PCI pool.

 Here's the log to the netconsole dmesg capture, I've used

 I did the usual suspend/resume cycle with i3lock, it hung after the

I have had a conversation with oiaohm over IRC about this, some
interesting things he had said about this issue:

2017-03-18 18:08:02 oiaohm  That driver that was going dead
because because it was physical port less was usb stack.   So maybe it
that bit of hardware still doing stupid.

2017-03-18 18:21:44 oiaohm  I guess this current log of yours is
with the realtek memstick black listed.
2017-03-18 18:21:55 oiaohm  because it does not exist.
2017-03-18 18:22:09 oiaohm  physically.

2017-03-18 18:23:04 oiaohm  Maybe.   If the hardware is not inited
the usb stack might not try to suspend it.

2017-03-18 18:26:30 oiaohm  No matter how you look at it the thing
is broken hardware.   I don't know if that realtek is USB 3.0
2017-03-18 18:27:02 oiaohm  Or it sitting on a USB 3.0 hub inside
the machine.

2017-03-18 18:27:39 oiaohm  You cannot expect a driver to work
when the hardware is portless.
2017-03-18 18:27:51 oiaohm  and it should have a port.
2017-03-18 18:27:52 oiaohm  either.

2017-03-18 18:29:03 oiaohm  rtsx_usb_ms this is a memstick driver
there should be  memstick port on you system or a header for a
memstick port both mean the pull down and pull up circiuts are present
so the hardware cannot function right.
2017-03-18 18:29:38 oiaohm  You gone over the machine and there is
no memstick port exposed being a laptop the odds of internal header is
basically never happens.
2017-03-18 18:30:27 oiaohm  so it broken hardware.
2017-03-18 18:31:18 oiaohm  the correct answer with broken
hardware is don't init the part blacklist the driver.

2017-03-18 18:40:36 oiaohm  You can think of it this way the
hardware gets lost because it cannot tell if something is connected so
is sending messages and waiting for responses that will never come.
But when hardware is there due to different speeds of cards it has no
clear clue what the time frame is.
2017-03-18 18:41:27 oiaohm  So the hardware being lost and kinda
jammed is purely to be excepted if it does not have all it required
circuits to function.

2017-03-18 18:48:42 oiaohm  You have the realtek controller for a
memstick port and it cannot tell if the proper hardware is present or
not that is what is triggering the driver to load.
2017-03-18 18:49:18 oiaohm  There is a difference when you have
the USB 3.0 controller active.
2017-03-18 18:49:49 oiaohm  You will see a lot of windows users
noting they need to disable the USB 3.0 controller to hibernate.
2017-03-18 18:50:19 oiaohm  In usb 2.0 the operating system polls
the USB ports and does a lot of the messaging.   In USB 3.0 controller
it does that polling.
2017-03-18 18:50:40 oiaohm  USB 3.0 controllers normally presume
all the hardware that is inited is functional.
2017-03-18 18:51:07 oiaohm  Linux kernel doing USB 2.0 polling
itself presumes the hardware could be busted.
2017-03-18 18:56:37 oiaohm  USB 3.0 controller is interpret driven
to the OS so it does a lot of heavy lifting of USB by itself. USB
2.0 and before controllers are like win modems basically brainless and
depending on the OS todo everything thing.

2017-03-18 18:58:27 oiaohm  So usb 2.0 controller not showing the
issue and the usb 3.0 showing the issue is kind of expected.   If you
did not init the hardware and usb 3.0 controller still showed a issue
then there would be a problem.
2017-03-18 19:02:59 oiaohm  dviola I guess the only thing you were
missing is that the USB 3.0 controller had proper controller so can
think for itself and USB 2.0 and before is like a brainless winmoden
so the OS can work around a few USB hardware issues in USB 2.0
controller mode.

2017-03-18 19:09:58 oiaohm  do remember the difference between usb
2.0 and usb 3.0 at times you have no choice but to force back to usb
2.0
2017-03-18 19:10:12 oiaohm  With broken bits of hardware.

2017-03-18 22:30:38 oiaohm  I think everyone is being confused by
a basic hardware construciton cost cutting move.
2017-03-18 22:31:18 oiaohm  Now maybe they will be able
