From b2529be317f8879fc5b6b8341db37ab58e90d017 Mon Sep 17 00:00:00 2001 From: Jinjie Ruan Date: Mon, 30 Sep 2024 17:19:13 +0800 Subject: [PATCH] i3c: master: svc: Fix pm_runtime_set_suspended() with runtime pm enabled commit 18599e93e4e814ce146186026c6abf83c14d5798 upstream. It is not valid to call pm_runtime_set_suspended() for devices with runtime PM enabled because it returns -EAGAIN if it is enabled already and working. So, call pm_runtime_disable() before to fix it.
