Sebastian Andrzej Siewior 97b31c1f8e leds: trigger: Disable CPU trigger on PREEMPT_RT ... The CPU trigger is invoked on ARM from CPU-idle. That trigger later invokes led_trigger_event() which may invoke the callback of the actual driver. That driver can acquire a spinlock_t which is okay on kernel without PREEMPT_RT. On a PREEMPT_RT enabled kernel this lock is turned into a sleeping lock and must not be acquired with disabled interrupts. Disable the CPU trigger on PREEMPT_RT.
