From 4dd8752a14ca0303fbdf0a6c68ff65f0a50bd2fa Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 13 Jul 2023 16:57:41 +0200 Subject: [PATCH] serial: qcom-geni: drop bogus runtime pm state update The runtime PM state should not be changed by drivers that do not implement runtime PM even if it happens to work around a bug in PM core. With the wake irq arming now fixed, drop the bogus runtime PM state update which left the device in active state (and could potentially prevent a parent device from suspending).
