Is object_idr a field that already exists? If so, "Rename" is not the
best choice of words. It should be something like "use the object_idr
field instead of the crtc_idr field" and then explain why. "task
description in TODO list for KMS cleanups" isn't very helpful to
understand why the change should be made.

Hi Julia,
Thank you for your review!
This patch is to solve this TODO task:
drm_mode_config.crtc_idr is misnamed, since it contains all KMS object.
Should be renamed to drm_mode_config.object_idr.
Do you think I need to use this description in my commit message?
Best,
Shayenne

That seems more helpful.
But it seems that the name should actually be changed. Which means that
the structure definition should be changed too. Was that done?

Yes, you are right. I did not add the header file.
Thanks again!

Hi Shayenne,
Welcome to DRM.
As far as I can see you're a newcomer to kernel development, so I'd
recommend watch a recent talk from Marc [1]
He provides a very good introduction, both for newbies and for people
willing the know the deeper reasons behind.
That said, here's some suggestions:

The "... as ... to KMS cleanups" translation is very strange in
English. It confused me and I've read the TODO over a dozen times ;-)

As pointed out in the talk - always self review and ensure patches
don't break things.
Here, DRM doesn't build which is obviously not correct and breaks things.

Compilation should have given an error message. If you thought you
compiled, then you don't have the right configuration to actually compile
the code that you changed.
