Subject: [PATCH] watchdog: rti-wdt: Add missing pm_runtime_disable() in probe function
Git-commit: d055ef3a2c6919cff504ae3b710c96318d545fd2
Patch-mainline: v5.18-rc1
References: git-fixes
If the probe fails, we should use pm_runtime_disable() to balance
pm_runtime_enable().
Fixes: 2d63908bdbfb ("watchdog: Add K3 RTI watchdog support")
