Unfortunately drm moves pretty fast, so already a conflict when I tried to apply this. Some drivers are also in their own trees, so this might lead to more fun :-/ Can you pls split it up per-driver (just the directories under drivers/gpu/drm/ is enough)? Final patch to remove the function might then get stalled a bit ofc. Also can you pls update ./scripts/coccinelle/api/drm-get-put.cocci and remove that spatch hunk in the final patch, since we no longer need it?

I was planning to send patches to remove all remaining reference/unreference functions by the weekend [as there aren't much remaining now and I see that new drivers keeps adding them instead of new API]. So, wanted to delete whole cocci file after that. I thought of dividing a patch per function because Laurent requested to send a single patch for all files. But if we are going to split it per driver under gpu/drm, would it work if per driver patch contains all function cases? Also, would you be fine with taking a patch for removal of coccinelle file via your tree? Then I can include that in the same patchset as well.

It's been a while since we introduced drm_dev{get/put} functions to replace reference/unreference in drm subsystem for the consistency purpose. So, with this patch, let's just replace all current use cases of drm_dev_unref() with drm_dev_put and remove the function itself. Coccinelle was used for mass-patching.
