Subject: ALSA: hdac: Explicitly add io.h
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=42f2bb1c494543084b764e1ca253c73db910daf2;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ALSA: hdac: Explicitly add io.h

Compiling the hdac extended core on arm fails with below error:

  sound/hda/ext/hdac_ext_bus.c: In function 'hdac_ext_writel':
>> sound/hda/ext/hdac_ext_bus.c:29:2: error: implicit declaration of
>> function
+'writel' [-Werror=implicit-function-declaration]
     writel(value, addr);
     ^
   sound/hda/ext/hdac_ext_bus.c: In function 'hdac_ext_readl':
>> sound/hda/ext/hdac_ext_bus.c:34:2: error: implicit declaration of
>> function
+'readl' [-Werror=implicit-function-declaration]
     return readl(addr);

This is fixed by explicitly including io.h

Fixes: 99463b3a3994 - ('ALSA: hda: provide default bus io ops extended hdac')
