Subject: patch "xhci: Add missing CAS workaround for Intel Sunrise Point xHCI" added to usb-linus
Date: Mon, 01 Oct 2018 17:59:20 -0700 [thread overview]
Message-ID: <15384419606389@kroah.com> (raw)
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:
