Series omapdrm: Reverse direction of DSS device (dis)connect operations | expand

Commit Message

Laurent Pinchart Aug. 6, 2018, 12:27 a.m. UTC 
The omap_dss_device.dispc_channel_connect field is used by DSS outputs
to fail the .enable() operation if they're not connected. Set the field
directly from the (dis)connect handlers of the DSS outputs instead of
going through the CRTC dss_mgr operations.
