All, I took another look at this patch and realized it was missing a #include. I've added the appropriate #include to a new version of the patch.
Thanks,
Mike Salvatore

Subject: [PATCH] Input: xpad - send control init message to certain Xbox
controllers
The Xbox controller with idVendor == 0x045e and idProduct == 0x028e
requires that a specific control transfer be sent from the host to the
device before the device will send data to the host.
This patch introduces an xboxone_control_packet struct and a mechanism
for sending control packets to devices that require them at
initialization.
