From: Johan Hovold Date: Fri, 21 May 2021 13:28:39 +0000 (+0200) Subject: media: gspca/sq905: fix control-request direction X-Git-Tag: Ubuntu-5.15.0-12.12~2418^2~143 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=53ae298fde7adcc4b1432bce2dbdf8dac54dfa72;p=mirror_ubuntu-jammy-kernel.git media: gspca/sq905: fix control-request direction The direction of the pipe argument must match the request-type direction bit or control requests may fail depending on the host-controller-driver implementation. Fix the USB_REQ_SYNCH_FRAME request which erroneously used usb_sndctrlpipe(). Fixes: 27d35fc3fb06 ("V4L/DVB (10639): gspca - sq905: New subdriver.")
