From f4e3040bf0e94ff86ba2c970a4d7691100dc69d5 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 10 Dec 2015 13:01:28 +0100 Subject: [PATCH] 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.
