From d27fc5ba46fc01cf1501c0ec54436c202f5d4235 Mon Sep 17 00:00:00 2001 From: Tao Zhang Date: Thu, 19 Aug 2021 17:29:37 +0800 Subject: [PATCH] coresight: cti: Correct the parameter for pm_runtime_put commit 692c9a499b286ea478f41b23a91fe3873b9e1326 upstream. The input parameter of the function pm_runtime_put should be the same in the function cti_enable_hw and cti_disable_hw. The correct parameter to use here should be dev->parent.
