Hi Avinash,
This look good to me except the: status = "disabled".
The "disabled" should be reserved for variant that does not contain the IP.
Is it the case here?

The LP855x family devices support the PWM input for the backlight control.
Period of the PWM is configurable in the platform side.
Platform specific functions are unnecessary anymore because
generic PWM functions are used inside the driver.
(PWM input mode)
To set the brightness, new
The mutex for accessing lp855x registers is used in case of
the user-space interaction.
When the brightness is changed via the sysfs, the mutex is required.
But the backlight class device already provides it.
Thus, the lp855x mutex is unnecessary.

Hi Dave.
Test Procedure:
1) Local USB disk WRITE speed on NFS server is ~25 MB/s
2) Run WRITE test(create 1 GB file) on NFS Client with default
writeback settings on NFS Server. By default
bdi->dirty_background_bytes = 0, that means no change in default
writeback behaviour
3) Next we change
v4:
1) a couple of coding style fixes (lines over 80 characters)
v3:
1) hash calculation simlified to improve perfomance.
v2:
1) Hash table become RCU-friendly. Hash table search now done under RCU lock
protection.

Add device tree support to matrix keypad driver by adding all necessary
DT parameters. Also added device tree bindings.
These patches were tested on AM335x-EVM with DT patches, DT patches
will be submitted once these are accepted.

device_release().
Device 'node2' does not have a release() function, it is broken and must
be fixed.
