[PATCH 2/2] gpio: mockup: use irq_sim_fire_edge()

[Bartosz Golaszewski <brgl@bgdev.pl>]

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

We now have a specialized variant of irq_sim_fire() - use it in
gpio-mockup so that we only generate events of types that were
requested with the LINEEVENT ioctl().
