Subject: [012/111] drivers/video/w100fb.c: ignore void return value / fix build failure

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Peter Huewe <peterhuewe@....de>

commit fa260c00c1aa5c657793a7221e40d2400df5afd8 upstream.

Fix a build failure "error: void value not ignored as it ought to be"
by removing an assignment of a void return value.  The functionality of
the code is not changed.
