mfd: Read wm831x AUXADC conversion results before acknowledging interrupt Ensure that there's no possibility of loosing an AUXADC interrupt by reading the conversion result in the IRQ handler when using interrupts. Otherwise it's possible that under very heavy load a new conversion could be initiated before the acknowledgement for a previous interrupt has happened.
