Linus Walleij daa3736151 backlight: ktd253: Stabilize backlight ... Remove interrupt disablement during backlight setting. It is way to dangerous and makes platforms instable by having it miss vblank IRQs leading to the graphics derailing. The code is using ndelay() which is not available on platforms such as ARM and will result in 32 * udelay(1) which is substantial. Add some code to detect if an interrupt occurs during the tight loop and in that case just redo it from the top.
