[git] drm-fixes

[Dave Airlie]

Hi Linus,

Please pull the 'drm-fixes' branch from
ssh://master.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6.git drm-fixes

This is just the simplest bug fixes that have showed up since rc1. It has 
one non-drm change to hide the old intelfb driver under CONFIG_EMBEDDED
and have it conflict with i915 kms code.

I've got an update for the radeon kms+ttm staging driver, that I'll
send a pull request for separately. I'm just confirming it doesn't touch 
anything outside the staging code.

Dave.

    drm: Move a dereference below a NULL test
    
    If the NULL test is necessary, then the dereference should be moved below
    the NULL test.
    
    The semantic patch that makes this change is as follows:

    fb/intelfb: conflict with DRM_I915 and hide by default
    
    Users get confused by this driver.  It's really a special purpose
    embedded driver, and causes a lot of problems if enabled.  So hide it
    under EMBEDDED by default, and make sure it doesn't get enabled with
    the i915 DRM driver.
    
    Dave, I'm hoping you can feed this to Linus through your tree.  It's
    appropriate for 2.6.31 I think.

    drm/via: Fix vblank IRQ on VIA hardware.
    
    via_enable_vblank wasn't setting the VBlank enable bit - instead, it
    was masking out the rest of the register.
    
    At the same time, fix via_disable_vblank to clear the VBlank enable
    bit.
