You can put
  if SND_SOC_SOF
at this point.  This will reduce lots of "depends on SND_SOC_SOF"
lines.

... the endif for SND_SOC_SOF can be put here, then both Kconfigs are
covered by SND_SOC_SOF condition.


OTOH, the usage of if-block below is an overkill.

For single items, just use depends on.  It's easier to read.
