[PATCH 0/2] hid-asus: reset the backlight brightness level on resume

[Luke D. Jones]

From: Denis Benato <benato.denis96@xxxxxxxxx>

I have noticed that in my Asus device RC71L the keyboard backlight is LEDs brightness of two RGB rings around two joysticks of this handheld device.

The firmware on this device (and other devices from the same manufacturer) restores a default brightness level (that is full brightness for my device and off for some others) after resuming from sleep; that means sysfs will report a wrong brightness level and requires human intervention to restore the desired brightness.

I have fixed aforementioned problems with this patch I am submitting.

This patch (composed of two distinct patches) compiles without warnings on both gcc and clang and also improves a function signature and constant-correctness of the kernel driver.
