This is a note to let you know that I've just added the patch titled
usb: udc: core: add device_del() call to error pathway
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: udc: core: add device_del() call to error pathway
This patch fixes a bug in the error pathway of
usb_add_gadget_udc_release() in udc-core.c. If the udc registration
fails, the gadget registration is not fully undone; there's a
put_device(&gadget->dev) call but no device_del().
