[...] I think it would be nice if you could submit a patch to remove the drivers from ASoC, then we can see if anybody complains.
Also the same thing for v3.17-rc5 and next-20140918. So let's see if we can remove this driver too.
Done on top of next-20140918. Again untested. -------->8-------- From: Paul Bolle pebolle@tiscali.nl
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".
