I made the v2 (as per above build stats) but never sent it out since I
wasn't sure if mfd wanted a complete resend (like davem/linux-net) or
just resends of the revised content... and then I never came back to it.

Here is the one line trivial patch.  If you want to punt this to 4.9
given the current timing wrt. the merge window, feel free to do so;
and/or I can re-send it myself with other pending 4.9 content I have.

Thanks,
Paul.

Subject: [PATCH] mfd: as3722: convert MFD_AS3722 from bool to tristate

The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config MFD_AS3722
drivers/mfd/Kconfig:    bool "ams AS3722 Power Management IC"

...meaning that it currently is not being built as a module by anyone.

In response to an earlier patch set suggesting removal of the unused
modular code, Laxman suggested that this driver be instead moved to
tristate.

We do that here, and confirm it can build and modpost as a tristate.
However there remains to be runtime testing in order to ensure this
change is 100% functional for "=m".
