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. >>From 41318a2b82f5d5fe1fb408f6d6e0b22aa557111d Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Fri, 12 May 2017 12:06:32 +0200 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.
