I can easily see how this prevents adding SND_IMX_SOC to a config if
SND_SOC_TEGRA is enabled, but I'm not sure about the other way around;
does Kconfig check that adding a new SND_SOC_TEGRA wouldn't invalidate
any of the depends of any already-selected options?
In other words, do you need to make the "same" change to Tegra?
