[PATCH 1/2] mfd/mc13783: new function exposing flags

[Uwe Kleine-König]

This is needed for the mc13783-adc driver to decide if a touch screen is
connected.  If so some channels are not available as generic hwmon inputs.

[PATCH 2/2] hwmon/mc13783-adc: don't access struct mc13783 directly

[Uwe Kleine-König]

There is a shiny new mc13783 API function that can be used instead.

While at it refactor the code a bit to reduce code duplication a bit.

This removes the last user of <linux/mfd/mc13783-private.h> and so this
include file can go away.

That's correct, patch applied.
As I said, we can now move mc13783-private.h to drivers/mfd/

Cheers,
Samuel.

Actually I'd fold it into mc13783-core.c.

And I didn't do it at once because I didn't expect you to take the hwmon
change via your tree.  Will send a patch later.

Best regards
Uwe
