[PATCH] ASoC: rockchip: i2s: Add dependency to I2S device driver

[Andreas Ruprecht]

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.
