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

xhci: Add missing CAS workaround for Intel Sunrise Point xHCI

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 workaround for missing CAS bit is also needed for xHC on Intel sunrisepoint PCH. For more details see:
