3.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ming Lei <ming.lei@canonical.com>
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'.
