4.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vinod Koul <vinod.koul@xxxxxxxxx>
commit 42f2bb1c494543084b764e1ca253c73db910daf2 upstream.
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
