Subject[2.6 patch] small MCA cleanups (fwd)

The patch forwarded below still applies and compiles against
2.6.10-rc2-mm3.

Please apply.


----- Forwarded message from Adrian Bunk <bunk@stusta.de> -----

Date: Sun, 7 Nov 2004 13:11:12 +0100

Subject: [2.6 patch] small MCA cleanups

The patch below does the following cleanups in the MCA code:
- make some needlessly global code static
- remove three unused global functions from mca-legacy.c (two of them
were EXPORT_SYMBOL'ed); this should IMHO be safe since mca-legacy
is not an API drivers should move to
