Subject[PATCH 5.10 561/599] watchdog: rti-wdt: Add missing pm_runtime_disable() in probe function
Date
From: Miaoqian Lin <linmq006@gmail.com>

commit d055ef3a2c6919cff504ae3b710c96318d545fd2 upstream.

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

Fixes: 2d63908bdbfb ("watchdog: Add K3 RTI watchdog support")
