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.
Thanks!
