I recall I provided the same comment as last time, but may remember
wrong.

New bridge drivers shall support that connector creation is optional.
This driver does not do that - see following code snippet:

+ if (flags & DRM_BRIDGE_ATTACH_NO_CONNECTOR) {
+ DRM_ERROR("Fix bridge driver to make connector optional!");
+ return -EINVAL;
+ }
+

I did not check, but likely the drive needs to implment some of the
connector hooks too. (detect, get_edid, etc).

Please include a changelog too - it can be very hard to remember what
feedback was provided when one reviews several patches/week.

Sam
