5.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Wentao Liang [ Upstream commit a8b8881d0c1aff544fae190469d86db7b07f43a9 ] pm_runtime_get_sync() keeps the runtime PM usage counter elevated even when it returns an error, so the reference taken at the beginning of wlcore_remove() has to be dropped on every exit path. When the device was not initialized the function returned early without doing so, leaking the reference. Release it with pm_runtime_put_noidle() as done on the other early error paths of this driver.
