From 8781ba7f45695af3ab8e8d1b55a31f527c9201a3 Mon Sep 17 00:00:00 2001 From: Aren Moynihan Date: Thu, 8 Dec 2022 17:02:26 -0500 Subject: mfd: axp20x: Fix order of pek rise and fall events The power button can get "stuck" if the rising edge and falling edge irq are read in the same pass. This can often be triggered when resuming from suspend if the power button is released before the kernel handles the interrupt. Swapping the order of the rise and fall events makes sure that the press event is handled first, which prevents this situation.
