Subject: [PATCH 05/15] ASoC: nuc900: export nuc900_ac97_data

From: Arnd Bergmann <arnd@...db.de>

The symbol "nuc900_ac97_data" is used by the nuc900_pcm driver, 
which may be a loadable module, so we should export it.

If one tries to build SND_SOC_NUC900 without SND_SOC_NUC900_AC97,
the kernel fails to link because of the reference to nuc900_ac97_data.
