This is a note to let you know that I've just added the patch titled
usb: musb: core: fix failure path
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-next branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will also be merged in the next major kernel release

Subject: usb: musb: core: fix failure path
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'.
