From: Gabriele Mazzotta Date: Tue, 23 Dec 2014 18:59:23 +0000 (-0800) Subject: leds: Don't allow brightness values greater than max_brightness X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=56d06fdee534124f79b51ff92232373b783cddc2;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git leds: Don't allow brightness values greater than max_brightness 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.
