Subject: [PATCH] soc: ti: knav_qmss_queue: Fix PM disable depth imbalance in knav_queue_probe
Git-commit: e961c0f19450fd4a26bd043dd2979990bf12caf6
Patch-mainline: v6.2-rc1
References: git-fixes
The pm_runtime_enable will increase power disable depth. Thus
a pairing decrement is needed on the error handling path to
keep it balanced according to context.
Fixes: 41f93af900a2 ("soc: ti: add Keystone Navigator QMSS driver")
