This is a note to let you know that I've just added the patch titled
usb: musb: dsps: start OTG timer on resume again
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-linus 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 hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: usb: musb: dsps: start OTG timer on resume again
Commit 468bcc2a2ca ("usb: musb: dsps: kill OTG timer on suspend") stopped
the timer in suspend path but forgot the re-enable it in the resume
path. This patch fixes the behaviour.
