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.
