ASoC: codec registers with more than 16 bits.

ASoC: codec registers with more than 16 bits.

[Daniel Ribeiro]

Hello alsa experts,

	I am working on a ASoC codec driver for the Motorola PCAP2
ASIC for the OpenEZX project, and i am having some trouble...

	PCAP2 has 25 bits registers, I access these registers via
32 bits SPI writes/reads, but soc-core/soc-dapm expects codec
registers values to fit on 'unsigned short' vars.

	Is there any reason to this limit? I am currently faking
the registers to always fit 16 bits, but this looks ugly.

	Would a patch to soc-core/dapm to extend this limit to
32 bits registers be accepted?

	Thanks!

No reason other than nobody needed it before.

Of course - that'd be great, but note that all the codec drivers will
need updating to match the API change.
