Subject: [PATCH 2/4] ASoC: samsung: Remove PCM support for WM8580 on SMDK
Commit 28c8331d386a ("ARM: S5PV210: Remove support for board files")
removed the Kconfig symbols MACH_SMDKC110 and MACH_SMDKV210. As a result
the dependencies of SND_SOC_SMDK_WM8580_PCM can never be met. So remove
the unbuildable "SoC PCM Audio support for WM8580 on SMDK".
Signed-off-by: Paul Bolle <pebolle@...cali.nl>

Suggested by Arnd Bergmann (see https://lkml.org/lkml/2014/9/4/381 ).
Previously submitted in https://lkml.org/lkml/2014/9/18/147 , but again
in an awkward way. So this is a resend too.
