Subject: [media] omap3isp: Don't fail streamon when the sensor doesn't implement s_stream Author: Laurent Pinchart <[email protected]> Date: Sat Aug 13 13:09:11 2011 -0300 The code handles subdevs with no s_stream operation correctly, but returns -ENOIOCTLCMD by mistake if the first subdev in the chain has no s_stream operation. Return 0 in that case.
