Subject[PATCH] gpio: sim: mark the GPIO chip as a one that can sleep
Date
From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

Simulated chips use a mutex for synchronization in driver callbacks so
they must not be called from interrupt context. Set the can_sleep field
of the GPIO chip to true to force users to only use threaded irqs.
