[alsa-devel] Bad rever-select of CONFIG_SND_HDA_I915

Hi,

while build testing, I noticed the following warning: warning: (SND_SOC_INTEL_SKYLAKE) selects SND_HDA_I915 which has unmet direct dependencies (SOUND && !M68K && !UML && SND && DRM_I915 && SND_HDA_CORE)

And it's indeed broken: you can't select CONFIG_SND_HDA_I915 from the driver side. This is the condition depending on DRM i915 driver.

Fixing this doesn't look too trivial, though. Since SND_SOC_INTEL_SKYLAKE is the item to be selected, it can't have "depends on". So, the top-level configs that select SND_SOC_INTEL_SKYLAKE need to have "depends on DRM_I915" lines, or modify the driver to be built without i915 binding.
