Gatien ChevallierandGreg Kroah-Hartman 2e42f29f0c Input: gpio-keys - fix possible concurrent access in gpio_keys_irq_timer()

commit 8f38219fa1 upstream.

gpio_keys_irq_isr() and gpio_keys_irq_timer() access the same resources.
There could be a concurrent access if a GPIO interrupt occurs in parallel
of a HR timer interrupt.

Guard back those resources with a spinlock.

Fixes: 019002f20c ("Input: gpio-keys - use hrtimer for release timer")
