Migrating everyone but the real tricky uses (alias >=2 functions to one
weak dummy) to the <linux/compiler.h> semantics is something on my TODO
list from ages ago.  So yes please, unless it's a complex case, find and
use the __shortform that <linux/compiler.h> and company provide (and a
git grep for your attribute when in doubt, sometimes it's in
<linux/compiler-gcc.h or so).

And a general I know everyone should know but please, checkpatch.pl your
work before posting.  Getting everyone doing DM series patches to use
patman might be a little bit more overhead (sorry!) but it'll help with
a lot of the little things like formatting and some of the bigger things
like changelog tracking.  Don't have to switch but it might make your
lives easier.
