[PATCH 5.10 561/599] watchdog: rti-wdt: Add missing pm_runtime_disable() in probe function

From: Greg Kroah-Hartman
Date: Tue Apr 05 2022 - 16:23:42 EST


From: Miaoqian Lin <linmq006@xxxxxxxxx>

commit d055ef3a2c6919cff504ae3b710c96318d545fd2 upstream.

If the probe fails, we should use pm_runtime_disable() to balance
pm_runtime_enable().
