- Do not clear V4L2_FL_USES_V4L2_FH flag because this flag indicates that file->private_data points to &struct v4l2_fh. - Initialize v4l2 ctrl handler with driver ctrl handler. - Add ctrl ops for g_volatile_ctrl to return updated value of volatile ctrls from driver. Fixes: v4l2-compliance: testPrio (VIDIOC_G/S_PRIORITY). testQueryControls (VIDIOC_QUERYCTRL).
