X-Git-Tag: v2.6.35.5~61 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=25de680b83ee668dd4d7c3d530217cb70cf58833;p=karo-tx-linux.git HID: Set Report ID properly for Output reports on the Control endpoint. commit c29771c2d8ceb907ed45eb8c7fc0450308140aca upstream. When I made commit 29129a98e6fc89 ("HID: Send Report ID when numbered reports are sent over the control endpoint"), I didn't account for *buf not being the report ID anymore, as buf is incremented.
