Subject: usb: musb: core: fix failure path
From: Ming Lei <ming.lei@xxxxxxxxxxxxx>
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'.
