The of_node_put() function tests whether its argument is NULL and then
returns immediately. Thus the test around the calls is not needed.
This issue was detected by using the Coccinelle software.

Hi,
I would like to have some feedback for these two patches. I have two questions.
1.
To suppress the warnings telling me I have no vmmc and vqmmc supplies, I have
added them and discovered that adding a vmmc supply involve only writing 1 in
the Power Control Register involves enabling the SD B
When there is a vmmc regulator, only SD Bus Power is set to 1 in the
Power Control Register. It means SD Bus Voltage Select field is set to 0
that is a reserved value. The SD Host Controller specification says:
'SD Bus Power: Before setting this bit, the SD Host Driver shall set SD
Bus Voltage Sele
Add vmmc and vqmmc regulators for sdhci devices.
The voltage for sdmmc0 vqmmc is selected by a signal from coming from
the sdhci device.

The kobject_put() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

Hi,
This is a basic framework for supporting polled IO with the block
layer stack, and added support for sync O_DIRECT IO and the NVMe
driver.
There are a few things missing to truly productize this, but it's
very useful for testing. For now, it's a per-device opt-in feature.
To enable it, you ec

Add basic support for polling for specific IO to complete. This uses
the cookie that blk-mq passes back, which enables the block layer
to pass this cookie to the driver to spin for a specific request.
This will be combined with request latency tracking, so we can make
qualified decisions about whe
Add nvme_poll(), which will check a specific completion queue for
command completions. Wire that up to the new block layer poll
mechanism.
Later on we'll setup specific sq/cq pairs that don't have interrups
enabled, so we can do more efficient polling. As of this patch, an
IRQ will still trigger o
Return a cookie, blk_qc_t, from the blk-mq make request functions, that
allows a later caller to uniquely identify a specific IO. The cookie
doesn't mean anything to the caller, but the caller can use it to later
pass back to the block layer. The block layer can then identify the
hardware queue and
No functional changes in this patch, but it prepares us for returning
a more useful cookie related to the IO that was queued up.

The free_io_pgtable_ops() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
