Subject: [PATCH] wlcore: fix runtime pm imbalance in wlcore_regdomain_config
Git-commit: 282a04bf1d8029eb98585cb5db3fd70fe8bc91f7
Patch-mainline: v5.8-rc1
References: git-fixes
pm_runtime_get_sync() increments the runtime PM usage counter even
the call returns an error code. Thus a pairing decrement is needed
on the error handling path to keep the counter balanced.
