Fabrice Gasnier 664e5a6f54 Input: gpio-keys - fix a sleep while atomic with PREEMPT_RT ... commit f4a8f561d0 upstream. When enabling PREEMPT_RT, the gpio_keys_irq_timer() callback runs in hard irq context, but the input_event() takes a spin_lock, which isn't allowed there as it is converted to a rt_spin_lock(). [ 4054.289999] BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48 [ 4054.290028] in_atomic(): 1, irqs_disabled(): 1, non_block: 0, pid: 0, name: swapper/0 ...

Relax the hrtimer not to use the hard context.
