Pull request for MIPS-specific driver bits

Pull request for MIPS-specific driver bits

[Ralf Baechle]

Below three patches for MIPS-specific drivers that I can't get anybody
else interested in merging.  To be accurate drivers/video/gbefb.c is
shared with SGI's x86-based Visual Workstation which is more or less
the same system architecture than the MIPS-based O2.

Please pull them from

    git://ftp.linux-mips.org/pub/scm/upstream-linus.git upstream

This would be the last MIPS-related patches I have pending for 2.6.32.

Thanks,

  Ralf

    VIDEO: Correct use of request_region/request_mem_region
    
    request_region should be used with release_region, not request_mem_region.
    
    Geert Uytterhoeven pointed out that in the case of drivers/video/gbefb.c,
    the problem is actually the other way around; request_mem_region should be
    used instead of request_region.
    
    The semantic patch that finds/fixes this problem is as follows:

There are no driver updates there. It looks like you overwrote that branch 
with your other MIPS build fixes that you had a separate pull request for.

Correct - but that pull request was obsolete anyway as one of the driver
patches had independentaly submitted to both me and gregkh and you pulled
Greg's version yesterday.

I spun a new tree which again is at:

  git://ftp.linux-mips.org/pub/scm/upstream-linus.git upstream

Please pull, thanks!
