I shall assume that this patch was authored by Mario.  This should have
been communicated by adding his From: line right at the top of the
changelog.  Mario's signed-off-by: is absent, but that is tolerable
because we have yours.

The (absent) changelog fails to explain what effect this patch has. 
_why_ does this driver need this quirk?

As it stands, there is insufficient information here for making
2.6.28-vs-2.6.29 decisions, let alone 2.6.27.x, 2.6.26.x, etc.
