Subject: ALSA: hda - Optimize audio component check in patch_hdmi.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f4e3040bf0e94ff86ba2c970a4d7691100dc69d5;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ALSA: hda - Optimize audio component check in patch_hdmi.c

The audio component is enabled only when CONFIG_SND_HDA_I915 is set.
Give a dummy macro for allowing the compiler optimize out the relevant
codes when this Kconfig isn't set.
