This is a note to let you know that I've just added the patch titled

usb: gadget: f_uac1: stop playback on function disable

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.

There is missing playback stop/cleanup in case of gadget's ->disable callback that happens on events like USB host resetting or gadget disconnection
