Subject: [PATCH] gpio: arizona: handle pm_runtime_get_sync failure case
Git-commit: e6f390a834b56583e6fc0949822644ce92fbb107
Patch-mainline: v5.8-rc5
References: git-fixes

Calling pm_runtime_get_sync increments the counter even in case of
failure, causing incorrect ref count. Call pm_runtime_put if
pm_runtime_get_sync fails.
