[Intel-gfx] [PATCH 15/17] drm/kms-core: Use recommened kerneldoc for struct member refs
Daniel Vetter
daniel.vetter at ffwll.ch
Thu Dec 29 20:48:35 UTC 2016
I just learned that &struct_name.member_name works and looks pretty
even. It doesn't (yet) link to the member directly though, which would
be really good for big structures or vfunc tables (where the
per-member kerneldoc tends to be long).
Also some minor drive-by polish where it makes sense, I read a lot
of docs ...
