[PATCH 0/2] gpio: sim: lock simulated GPIOs as interrupts

[Bartosz Golaszewski <brgl@bgdev.pl>]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

I realized that the gpio-sim module doesn't lock the GPIOs as interrupts
when they are requested from the irq_sim. This leads to users being able
to change the direction of GPIOs that should remain as inputs to output.
This series adds a notifier to the interrupt simulator that users can
register with to be informed about interrupts being requested and
released so that they can act accordingly. The gpio-sim is made to use
this notifier and lock GPIOs as interrupts when needed.

Thomas: if this is fine with you, can you Ack it so that I can take it
through the GPIO tree for the next merge window?
