This is a note to let you know that I've just added the patch titled
usb: chipidea: ci_hdrc_imx: add missing put_device() call in
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.

if of_find_device_by_node() succeed, usbmisc_get_init_data() doesn't have a corresponding put_device(). Thus add put_device() to fix the exception handling for this function implementation.
