This is partly my fault for getting grumpy about adding the bolier plate
code without error checking - overall Linus' change to do the get in the
core seems like the most sane approach here.

Jean-Christophe has been most insistent that pinctrl support is now
manadatory for all AT91 systems using device tree.  Unfortunately
pinctrl support for AT91 only came in during the merge window and it
seems like it's sadly been impossible to do what seemd like the obvious
thing and add the pinctrl bindings to the DT prior to the merge down so
now we've got this mess.  I believe the way the pinctrl conversion was
done renders the audio driver non-functional without this series.

Like I say I'm not thrilled about ignoring the return code TBH, nor am I
thrilled with the way this has been handled overall.  That said, the
current series does seem like the best of a bad job - as I understand it
we need something like this in v3.8 to make the driver functional.
