Title
led: qcom-lpg: Fix sleeping in atomic
Summary
In the Linux kernel, the following vulnerability has been resolved: led: qcom-lpg: Fix sleeping in atomic lpg_brighness_set() function can sleep, while led's brightness_set() callback must be non-blocking. Change LPG driver to use brightness_set_blocking() instead. BUG: sleeping function called from invalid context at kernel/locking/mutex.c:580 in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 0, name: swapper/0 preempt_count: 101, expected: 0 INFO: lockdep is turned off.
