From 579ced8fdb00b8e94304a83e3cc419f6f8eab08e Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Wed, 4 Mar 2020 14:54:32 -0800 Subject: [PATCH] Revert "gpio: omap: Fix lost edge wake-up interrupts" This reverts commit a522f1d0c381c42f3ace13b8bbeeccabdd6d2e5c. With cpu_pm handling fixed for omaps, and with gpio-omap now returning notify error on pending interrupts, we can drop the old workaround for seeing if there may be pending edge interrupts.
