[PATCH] ASoC: tegra: SND_SOC_TEGRA_AUDIO_GRAPH_CARD should depend on SND_SOC_TEGRA
by Geert Uytterhoeven 01 Feb '21

01 Feb '21

Audio Graph Card based Tegra driver is only useful on NVIDIA Tegra SoCs. Hence add a dependency on SND_SOC_TEGRA, to prevent asking the user about this driver when configuring a kernel without Tegra sound support. Wrap all Tegra sound config options inside a big if/endif block, instead of just adding the dependency to the single config option that does not have it yet, to preventing similar future mistakes.
