Subject: staging/xgifb: Move register helper functions to header
X-Git-Tag: v4.3-rc1~158^2~634
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=fb44d9a507305ab05945d8a781a0a1255a3d9868;p=linux.git

staging/xgifb: Move register helper functions to header

and mark them as static inline.
This shrinks the compiled module from 137442 to 117732 bytes and we also
get rid of vb_util.c
