[PATCH 2/4] backlight: lm3630a: Don't set bl->props.brightness in get_brightness

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

 



There's no need to set bl->props.brightness, the get_brightness function
is just supposed to return the current brightness and not touch the
struct.

With that done we can also remove the 'goto out' and just return the
value.
