I assume you're referring to the prefix. Well, I'm actually trying to
set a trend there. :) Since there's no other amdgpu driver, the drm/ is
redundant. In the specific case of this patch, adding it would make the
shortlog too long, and IME it's quite often the case that those four
character cells could be put to better use than for the redundant prefix.
