Subject: [PATCH 5.15 848/913] watchdog: rti-wdt: Add missing pm_runtime_disable() in probe function

From: Miaoqian Lin <linmq006@...il.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")
