fwiw, here's how I review these:

First load a quickfix list using the following grep line:

Ggrep '\(plane\|primary\|cursor\)\S*\(fb\|crtc\)' -- drivers/gpu/drm/

But that includes the plenty of hits that do use state structs. So then I
filter for stuff without a preceeding state using vim's regexes:

\(plane\|primary\|cursor\)\(\S*state\S*\)\@!\S*\(->\|\.\)\(fb\|crtc\)

I'm feeling really bad about all this :-)

Cheers, Daniel
