From: Daniel Vetter Date: Thu, 1 Nov 2012 13:45:17 +0000 (+0100) Subject: drm/doc: integrate fb helper reference into docs X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d0ddc0338af8265e65bd5e4ca72e3d8e61e41d8d;p=linux-beck.git drm/doc: integrate fb helper reference into docs Again only minimal changes to make kerneldoc no longer shout. Plus a little introduction in the form of a inline DOC: section to quickly explain what this is all about. v2: Fixup spelling fail.
