[PATCH] leds: Don't allow brightness values greater than max_brightness

[Gabriele Mazzotta]

Since commit 4d71a4a12b13 ("leds: Add support for setting brightness in
a synchronous way") the value passed to brightness_set() is no longer
limited to max_brightness and can be different from the internally saved
brightness value.
