[PATCH 01/15] ASoC: CS42L51 and WM8962 codecs depend on INPUT

[Xia Kaixu]

From: Arnd Bergmann <arnd@arndb.de>

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. 

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.

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?

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,
Brian

Applied, but...

...please don't include noise like this in patch submissions, especially
with such long lists (which still manage to miss the driver maintainers
concerned).

I suspect it's ASoC built in and INPUT build as a module.

Ok, I'll try that next.
Doesn't IS_ENABLED cover that?

Apparently not.
I would like to come up with a better solution than making INPUT a requirement. I just need some time.
In the meantime I suppose it’s OK to apply it?

Yeah.  Realistically it's probably not going to ever be a practical
problem - the number of systems with audio but no input is likely to be
very close to zero.

Yeah, I'm just gonna go ahead and remove the #if's from the drivers then since it's required
