If $(CONFIG_KAPI_SPEC) is not set, shouldn't
obj-$(CONFIG_KAPI_SPEC) += api/
evaluate to
obj- += api/
anyways? Why the duplication? This is the only place in the kernel where
this would be needed?
yes, this is definitely not needed, as obj- is always evaluated during
'make clean', cp. scripts/Makefile.clean [1].
Kind regards

Thanks for the pointer!
The redundant "obj- += api/" and the accompanying comment are dropped in v4.
