From d66fbca6c1ac961bf7b0251b5735f2bc64d16c01 Mon Sep 17 00:00:00 2001 From: Jinjie Ruan Date: Mon, 9 Sep 2024 15:31:39 +0800 Subject: [PATCH] spi: geni-qcom: Undo runtime PM changes at driver exit time [ Upstream commit 89e362c883c65ff94b76b9862285f63545fb5274 ] It's important to undo pm_runtime_use_autosuspend() with pm_runtime_dont_use_autosuspend() at driver exit time unless driver initially enabled pm_runtime with devm_pm_runtime_enable() (which handles it for you). Hence, switch to devm_pm_runtime_enable() to fix it, so the pm_runtime_disable() in probe error path and remove function can be removed.
