patch "usb: gadget: uvc: fix dropped frame after missed isoc" added to usb-linus

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

usb: gadget: uvc: fix dropped frame after missed isoc

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: gadget: uvc: fix dropped frame after missed isoc

With the re-use of the previous completion status in 0d1c407b1a749 ("usb: dwc3: gadget: Return proper request status") it could be possible that the next frame would also get dropped if the current frame has a missed isoc error. Ensure that an interrupt is requested for the start of a new frame.
