[BUG]: Getting a unique connector name when identical displays are connected

Hello all,

This is regarding an issue I have encountered recently in drm. When I
connect two identical HDMI display(with same resolution) there is no way to
distinguish them uniquely.

I looked into that and found that the connector id, and connector_type_id
can be changed based on which connector appears first to the kernel.

Is there any solution already implemented for this problem?

I see following solution to this issue:

Assigning a unique connector->name from drm_connector_init() and adding an
api drmModeGetConnectorName().

Please let me know what you think..

Thanks in advance!
