Nathan Lynch 0b8728d6f1 ledtrig-cpu: kill useless mutex to fix sleep in atomic context ... Seeing the following every time the CPU enters or leaves idle on a Beagleboard: BUG: sleeping function called from invalid context at kernel/mutex.c:269 in_atomic(): 1, irqs_disabled(): 0, pid: 0, name: swapper/0 no locks held by swapper/0/0. [<c001659c>] (unwind_backtrace+0x0/0xf8) from [<c05aaa7c>] (mutex_lock_nested+0x24/0x380) [<c05aaa7c>] (mutex_lock_nested+0x24/0x380) from [<c043bd1c>] (ledtrig_cpu+0x38/0x88) [<c043bd1c>] (ledtrig_cpu+0x38/0x88) from [<c000f4b0>] (cpu_idle+0xf4/0x120) [<c000f4b0>] (cpu_idle+0xf4/0x120) from [<c07e47c8>] (start_kernel+0x2bc/0x30c) Miles Lane has reported seeing similar splats during system suspend. The mutex in struct led_trigger_cpu appears to have no function: it resides in a per-cpu data structure which never changes after the trigger is registered. So just remove it.
