From c5fecc66f9362c27bdb8926d385990a6963188fc Mon Sep 17 00:00:00 2001 From: Miaoqian Lin Date: Wed, 5 Jan 2022 09:21:13 +0000 Subject: [PATCH] watchdog: rti-wdt: Add missing pm_runtime_disable() in probe function commit 1387ff02f3d44c9cf0255872f0c869ffff05e2ec upstream. If the probe fails, we should use pm_runtime_disable() to balance pm_runtime_enable().
