Subject: [PATCH 31/77] drm/mediatek: convert dpi driver to use
|
|
drm_of_find_panel_or_bridge
|
|
|
|
Convert dpi driver to use drm_of_find_panel_or_bridge.
|
|
This changes some error messages to debug messages (in the graph core).
|
|
Graph connections are often "no connects" depending on the particular
|
|
board, so we want to avoid spurious messages. Plus the kernel is not a
|
|
DT validator.
