changing it to `if (upd9976->ira >= 0 && !upd9976->irq_mem) is logically ok, but it introduces more indentation for a large block of code...
Put it in a function if that's an issue.
OK.
These look like regular routing controls to me... If they do need to be set with magic writes they should be platform data but things like pseudo differential inputs are normally just represented as two single ended inputs for which userspace just happens to choose a path that looks differential.
The above DMIC output might fit routing control in some way, but I think the MIC2 configuration is hardware specific, this is not related to routing quite much. Let me check whether it's easy to be implemented as a routing control or platform data...
Really, this is *very* common - a pseudo differential input is just two single ended inputs that happen to be used to fake a differential input on a given board. It's likely that a board will use the same setup most of the time (though sometimes it does change) but they should still not be configuring this with magic register writes in the machine driver.
As this should not be configured in machine driver, I'll make it a control so that user is about to change it (this should only be set once, and leave it there untouched).
