Subject: [PATCH 5/6] ASoC: samsung: wm8994 depends on mfd_wm8994

Any driver that selects SND_SOC_WM8994 should also make sure that
MFD_WM8994 is set, since the codec relies on the mfd code:

  sound/built-in.o: In function `wm8994_read':
  last.c:(.text+0x20160): undefined reference to `wm8994_reg_read'
  sound/built-in.o: In function `wm8994_write':
  last.c:(.text+0x20e68): undefined reference to `wm8994_reg_write'

This adds the missing 'depends' statements to Kconfig, as found
during ARM randconfig tests.

I wasn't sure any more which version you wanted. Is this this right one?
