Hi Dimitry,

Source code from
git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input.git, branch
xpad, head d9be398afb2c3333716324352d062c50112e4e86.

After suspend (systemctl suspend) my xpad wireless controller is still
blinking. Tried "echo 2 > /sys/class/leds/xpad0/brightness" but it did
not work.
That said, I also tried the same xpad code but built for my current
kernel (4.3.0 from debian/sid): led is still blinking after resume but
this time the sysfs file is functional.

Hopefully I did not make a mistake in the build process...

Best regards,
Clement
