First, your patch does the correct things.

I investigated a bit and it looks like the sound/soc/omap/am3517evm.c
never worked in mainline since the patch below adding codec to
board-am3517evm.c wasn't applied by reason or another.

This means that you should split this patch into two and they can be
sent as independent patches. am3517evm.c change via alsa-devel
and board-am3517evm.c via linux-omap & linux-arm-kernel. Some comments
below.

This is ok and don't need anything else as the rest pieces from
original missing patch are added by another patches.

Subject for this part could be something like
"ASoC: AM3517: Update codec name after multi-component update".

Remember to cc ASoC maintainers Mark Brown and Liam Girdwood.

You could add my acks to splitted patches.
