But this is a bus-agnostic, separate module (not a driver in itself) that provides implementation to cs40l26-i2c or cs40l26-spi drivers, which do contain that macro as they should. This doesn’t appear to be an uncommon pattern.


I see now in the Makefile that it can be indeed built as module and
compiled on its own. It's fine then.
