I hadn't spotted this in your cs4270 patches but the device used should
be the I2C device, not the soc-audio device.  I'd also expect to see
this regulator setup done in arch/arm - the stuff I'd expect to see in
here is the resource claiming stuff.  Having it here is also fine, it's
just a little surprising.

Remove empty functions like this (I think this is the only one that's
left).

I'd still really prefer to see this as a regular I2C device driver with
the code in arch/arm (even if the driver itself ends up embedded in this
file, which is what GTA01 did for a similar situation) but I guess I'm
OK.  max9486_hwmon_info could be renamed, though.

Nothing ever reverses this (one of the reasons to shove this bit into
arch/arm :) ).
