[media] touptek: don't DMA at the stack As warned by smatch: drivers/media/usb/gspca/touptek.c:220 reg_w() error: doing dma on the stack (buff) drivers/media/usb/gspca/touptek.c:458 configure() error: doing dma on the stack (buff) This can fail, as the stack may not be in a memory that would allod DMA. So, use the usb_buf instead. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
