[alsa-devel] [PATCH] ASoC: simple-card: fix module load "unknown symbol" issue

[Kevin Hilman]

An ASoC driver using simple-card, when built as a module gets the
following error at module load time:

[   23.571873] simple_card_utils: Unknown symbol snd_soc_of_parse_daifmt (err 0)
[   23.712726] simple_card_utils: Unknown symbol snd_soc_of_parse_card_name (err 0)

fix this by including simple-card-utils.o symbols in the module build
its symols are resolved correctly.

Tested on Davinci DA850-EVM using snd_soc_edma, snc_soc_davinci_mcasp,
with all of ASoC built as modules.
