Actually, I noticed that I screwed this up for the other tmio drivers
as well.  Here's a patch that addresses them all (you can
ignore the previous patch).


From: Andres Salomon <dilinger@xxxxxxxxxx>

This silences warnings such as

drivers/video/tmiofb.c: In function 'tmiofb_hw_init':
drivers/video/tmiofb.c:270: warning: initialization discards qualifiers from pointer target type

These were added by me in commit 2a79bb1d.
