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

usb: add USB_QUIRK_DELAY_INIT for Logitech C922

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.

The Logitech C922, just like other Logitech webcams, needs the USB_QUIRK_DELAY_INIT or it will randomly not respond after device connection
