[PATCH 02/11] platform/x86: asus-wmi: Fix preserving keyboard, backlight intensity on load

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The error code and return value are mixed up. The intensity is always set
to 0 on load as kbd_led_read returns either 0 or negative value. To
reproduce set backlight to maximum, reload driver and try to increase it
using keyboard hotkey, the intensity will drop as a result. Correct the
implementation.
