Subject: patch "uwb: fix device quirk on big-endian hosts" added to usb-linus
Date: Wed, 17 May 2017 11:27:59 +0200 [thread overview]
Message-ID: <14950132791493@kroah.com> (raw)
This is a note to let you know that I've just added the patch titled
uwb: fix device quirk on big-endian hosts
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: uwb: fix device quirk on big-endian hosts
Add missing endianness conversion when using the USB device-descriptor
idProduct field to apply a hardware quirk.
