Subject: ALSA: hda - Reduce ifdef CONFIG_SND_HDA_I915
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=31c648e0d304bbfc49a4a22c6139718367f3fd8d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ALSA: hda - Reduce ifdef CONFIG_SND_HDA_I915

We're providing dummy functions for CONFIG_SND_HDA_i915=n, thus ifdef
can be reduced.  (But hda_i915_init() has to be fixed to return zero.)

This automatically fixes a compile warning:
  sound/pci/hda/hda_intel.c: In function 'azx_probe_continue':
  sound/pci/hda/hda_intel.c:1966:1: warning: label 'i915_power_fail' defined but not used [-Wunused-label]
