drm/omap: Determine connector type directly in omap_connector.c

pinchartl · tomba · commit 52c5dd2a7bed · 2018-09-03T16:13:29.000+03:00
Instead of determining the connector type from the type of the display's
omap_dss_device and passing it to the omap_connector_init() function,
move the type determination code to omap_connector.c and remove the type
argument to the connector init function. This moves code to a more
natural location, making the driver easier to read.
