One of the problems I face is that I find it hard to understand how this
stuff works in v3.10 (ie, before MACH_SMDKV310 and MACH_SMDKC210 were

See, if you scan v3.10:arch/arm/mach-exynos/mach-smdkv310.c you'll
notice the string "smdk-audio". If you grep that string you get a few
hits. But none in v3.10:sound/soc/samsung/smdk_wm9713.c. And if you scan
v3.10:sound/soc/samsung/smdk_wm9713.c for strings you'll find stuff like
"wm9713-hifi",  "wm9713-codec", and "soc-audio". But these don't show up
in v3.10:arch/arm/mach-exynos/mach-smdkv310.c. So it's not obvious how
these two files relate.

And I'm left wondering why SND_SOC_SAMSUNG_SMDK_WM9713 actually depends
on (among other symbols) MACH_SMDKV310 and MACH_SMDKC210 in v3.10.
