Apparently, the patch is not yet in mfd-next, so let me retract it: I
just realized we should rather do an exact name/asset-tags match here as
well (like for exar and stmmac).

Moreover, I'd like to rework the DMI matching along Andy's suggestion
and use native matching methods (dmi_system_id table) instead of the
current open-code one. Patches will follow soon.
