[PATCH 4.4 137/188] media: gspca/sq905: fix control-request direction

[Greg Kroah-Hartman]

From: Johan Hovold <johan@xxxxxxxxxx>

commit 53ae298fde7adcc4b1432bce2dbdf8dac54dfa72 upstream.

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.")
