It seems we have two drivers in mainline for da9055 on I2C.  We've got
one in sound/soc/codecs/da9055.c and one in drivers/mfd/da9055-i2c.c,
both registering themselves identically.  What's going on here?  Is this
a combined CODEC and PMIC, has someone decided to release two chips with
the same name or is one of the drivers misnamed?

OK, in that case the CODEC driver is just plain broken then.  Did anyone
actually test this stuff?  Please fix.

Yes, this is a combined CODEC and PMIC.

Yes, I think so. Actually the CODEC driver was merged before PMIC ino
main line and was tested at that time. I will check with PMIC team if
they did test with CODEC.

I guess the fix should be in PMIC, right?

Both drivers need to be changed.

OK. We will fix both of them.
Thanks for pointing this out.
