Unfortunately, my testing just found a new problem with this patch
applied, I had
not run enough randconfig tests on top of it:
sound/soc/atmel/atmel_ssc_dai.o: In function `atmel_ssc_set_audio':
atmel_ssc_dai.c:(.text+0x73c): undefined reference to `ssc_request'
sound/soc/atmel/atmel_ssc_dai.o: In function `atmel_ssc_put_audio':
atmel_ssc_dai.c:(.text+0x7be): undefined reference to `ssc_free'
This is for a configuration with SND_ATMEL_SOC_CLASSD=y
and CONFIG_ATMEL_SSC=n. Could you tell me whether that is a
sensible configuration that should work, or whether we need a dependency
on ATMEL_SSC in SND_ATMEL_SOC_CLASSD? I can't really tell
from the source code, but you probably know the answer.
