[alsa-devel] [PATCH] ASoC: core: Return -ENOTSUPP from set_channel_map() if no operation provided

[Srinivas Kandagatla]

It makes it easier for common code to work with snd_soc_dai_set_channel_map()
by distinguishing between operation not being supported and an error.
This is done inline with others snd_soc_dai.* apis.
