Hi,

This restores the behavior, so people don't need to waste time compiling stuff they don't need.

You are missing your signed-off-by
That is intentional because this is a RFC patch to gather the feedback as I am no expert in DRM and may miss something important.
Once people are happy with it, I plan to send a formal patch with Signed-off-by.
CONFIG_DRM is tristate.
Your patch requires everything under drivers/gpu/drm/ modular when CONFIG_DRM=m.
At least, drivers/gpu/drm/drm_mipi_dsi.c is built-in only.
I guess that is the reason why they use 'obj-y += drm/'.
In other words, if you are able to make all the drm code modular, your patch is applicable.
