Currently, CONFIG_SND_SOC_ROCKCHIP_I2S could also be selected
without having CONFIG_SND_SOC_ROCKCHIP enabled.

As this makes no sense (and breaks the build, when the option
CONFIG_SND_SOC_GENERIC_DMAENGINE_PCM - which would be selected by
CONFIG_SND_SOC_ROCKCHIP - is not enabled), a Kconfig dependency
is added to CONFIG_SND_SOC_ROCKCHIP_I2S. This will make the item
visible only if CONFIG_SND_SOC_ROCKCHIP is enabled.

This doesn't seem like an obvious fix - why is the fix not to put the
select on the I2S driver (which is the thing that actually depends on
the dmaengine stuff)?

I didn't look a lot further into it, I just saw the build error report
and from the other commits touching the Kconfig file it looked like
there could be more options in the future.

I will submit a v2 of the patch in a minute with the select for the
dmaengine support moved to the I2S option.

Regards,

Andreas
