Comment # 17 on bug 105880 from Chí-Thanh Christopher Nguyễn

Created attachment 138863 [details]
dmesg from kernel 4.15 with attachment 138831 [details] applied

So I applied this patch from bug 105596

The "Unsupported Connector type:14" message is gone, the "Unsupported Connector
type:5" is still there (as expected).

However the screen stays blank and the "[drm] Cannot find any crtc or sizes"
message sill comes.
