Well, I want to embed the input-ff.c into the input module too.

Indeed... There are these 4 options as far as I see:

1. Do this rename
2. Put all the code in input-ff.c to input.c
3. Make the input-ff a separate bool "module" and add
EXPORT_SYMBOL_GPL() for input_ff_event() which is currently the only
function in input-ff.c that is called from input.c
4. Rename the input "module" to something else, it doesn't matter so
much as almost everybody builds it as built-in anyway.

WDYT is the best one?
