Looks good to me, so:

As Takashi said it is not that nice that there is a bit of code churn by having to update all the existing users of e->reg and e->mask. But implementing this properly seems to cause even more code churn. And I think it will be done best in an effort to consolidate the kcontrol helpers and the DAPM kcontrol helpers by adding an additional layer of abstraction between the kcontrols and the hardware access that translates between the logical value and the physical value(s).
E.g. something like
struct kcontrol_ops { int (*read)(...); int (*write)(...); };
And then have one kind of ops for each kind of control type and at the high level only have put and get handlers for enums and for switches/volumes.
