Building ARM randconfig got into a situation where CONFIG_INPUT
is turned off and SND_SOC_ALL_CODECS is turned on, which failed
for two codecs trying to use the input subsystem. Some other
drivers also select one of these codecs and consequently need an
explicit dependency added.
I assume you mean the CS42L52 instead of the L51. INPUT is used for a BEEP
Generator but when I disable CONFIG_INPUT I do not get an error. Is there
any information available on what the error is?
Appending to the dependency list seems the easiest way out,
since this is not a practical limitation. If anyone really
needs to build these codecs for a kernel with no input support,
a more sophisticated solution can be implemented.
It shouldn't build the BEEP code without CONFIG_INPUT enabled as you can
use the CODEC without the BEEP enabled.
I believe the WM8962 is done the same way.
Thanks,
