[alsa-devel] [PATCH v2] ARM: Tegra: select MACH_HAS_SND_SOC_TEGRA_WM8903

[Stephen Warren]

CONFIG_SND_SOC_TEGRA_WM8903 is useful for many Tegra boards. To avoid the
ASoC tegra/Kconfig enumerating them all, instead have the Tegra machine
Kconfig select MACH_HAS_SND_SOC_TEGRA_WM8903 where appropriate, and have
SND_SOC_TEGRA_WM8903 depend on this.

Mark, this will need to be applied to your tegra branch so it can get
merged into both trees. Thanks.

v2: s/HAS/WANT/ in Kconfig variable name.
  I figured a machine "HAVING" a Kconfig variable didn't make much sense.
  I also wondered about ALLOW/ENABLE.
  Still, being consistent with existing variable naming is more important
  that the finer details of English:-)
