media: v4l2-async: Remove V4L2_ASYNC_MATCH_DEVNAME
The last user for this type of match was the soc-camera/sh_mobile_csi2 driver, which was removed in v4.9. If the support is ever needed, it can always be restored. [Sakari Ailus: Also drop DEVNAME from debug prints recently added.] Signed-off-by: Ezequiel Garcia <ezequiel@collabora.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
