Manfred Schlaegl c945cbcf45 leds: trigger: ledtrig-backlight: Fix invalid memory access in fb_event notification callback ... fb_notifier_callback is called on any event fired by fb_notifier_call_chain. Events may, or may not contain some data (fb_event.data). In case of FB_EVENT_BLANK fb_event.data contains a pointer to an integer holdingthe blank state. The Problem is, that in ledtrig-backlight.c - fb_notifier_callback the pointer to blank state is dereferenced BEFORE the event-type is checked. Obviously this leads to problems with other events than FB_EVENT_BLANK, where fb_event.data is undefined or NULL. It seems, that this problem existed ever since the driver was added. Like in drivers/video/backlight/backlight.c line 43 I would suggest to return immediately on events other than FB_EVENT_BLANK.
