If anyone has any objections, please let me know. ------------------ From: Ming Lei commit 681d1e8761ca773967bce9bd1bb2896f07279551 upstream. In the fail1~fail5 failure path, pm_runtime_disable() should be called to avoid 'Unbalanced pm_runtime_enable' error in next probe() which may be triggered by defer probe or next 'modprobe musb_hdrc'.
