Seems a missing sync from ums to kms. Thanks!

Right.

Hi, Eric
   Will you please pick up this patch?
   Otherwise the SDVO can't work well on G33 platform with KMS enabled.
   
thanks.

Hi, Eric
    Will you please also pick up the patch related with TV property in
this patch set?
    One is to set the TV_format based on connector type(integrated TV)
    The other three patches are to add the property for SDVO-TV(LVDS).

thanks.

No, that's not suitable at this point in the release cycle, and I'm
waiting for a couple of major patches for applying before I do the small
ones for -next.
