The kmap_atomic* interfaces in all architectures are pretty much the same
except for post map operations (flush) and pre- and post unmap operations.
Provide a generic variant for that.

Pointer np is being initialized with a value that is never read
and it is being updated with a value later on. The initialization
is redundant and can be removed.

Right, there's no need for "dev" at all actually. I kept "dev" just to
keep the code for updating "dev->stats" simpler, because otherwise we

Clients can register their callbacks for power-on/off notifications
of remote processors. While executing the notifier chain sometimes
these callbacks may get stuck or take a long time which is not desired.

Hello Paul,
Thanks for reviewing!
It seems from the comments in [PATCH 4/5] that the consensus would be to
drop allwinner,sun8i-s3 and keep sochip,s3 (I guess due to the fact that
the S3 is distributed by Sochip).
And yes, you're right that it makes sense to add allwinner,sun8i-v3 at
the end.

Use the DDC connection to read the EDID from the eDP panel instead of
relying on the panel to tell us the modes.

These register reads and writes are sometimes directly next to each
other in the register address space. Let's use regmap bulk read/write
APIs to get the data with one transfer instead of multiple i2c
transfers. This helps cut down on the number of transfers in the case of
something like reading
We should be setting the drm_dp_aux_msg::reply field if a NACK or a
SHORT reply happens. Update the error bit handling logic in
ti_sn_aux_transfer() to handle these cases and notify upper layers that
such errors have happened. This helps the retry logic understand that a
timeout has happened, or
There's no reason we need to wait here to poll a register over i2c. The
i2c bus is inherently slow and delays are practically part of the
protocol because we have to wait for the device to respond to any
request for a register. Let's rely on the sleeping of the i2c controller
instead of adding any
This patch series cleans up the DDC code a little bit so that
it is more efficient time wise and supports grabbing the EDID
of the eDP panel over the aux channel. I timed this on a board
I have on my desk and it takes about 20ms to grab the EDID out
of the panel and make sure it is valid.

Add the missing platform_device_unregister() before return
from zd1301_frontend_attach in the error handling case when
pdev->dev.driver is empty.
There's an error handling route named err_platform_device_unregister
, so just reuse it.

Chao, got it on f2fs_is_compress_algorithm_valid().
I also agree on Eric's opinion on that error value.

Hi all,
After merging the pinctrl tree, today's linux-next build (x86_64
allmodconfig) failed like this:
ERROR: modpost: "irq_gc_set_wake" [drivers/pinctrl/pinctrl-rockchip.ko]

I have reverted
While powering down, the device may or may not acknowledge an MHI
RESET issued by host for a graceful shutdown scenario and end up
sending an incoming data packet after tasklets have been killed.
If a rogue device sends this interrupt for a data transfer event
ring update, it can result in a
MHI client drivers can request a device wake even if the device
may be in an error state or undergoing a shutdown. To prevent
unnecessary device wake processing, check for the device state
and bail out early so that the clients are made aware of the
device state sooner.
