From: Maxime Ripard <maxime.ripard@xxxxxxxxxxxxxxxxxx> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit 259b77ef853cc375a5c9198cf81f9b79fc19413c upstream. The TCA8418 might be used using different interrupt triggers on various boards. This is not working so far because the current code forces a falling edge trigger. The device tree already provides a trigger type, so let's use whatever it sets up, and since we can be loaded without DT, keep the old behaviour for the non-DT case.
