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.")
