I am puzzled by this result, and trying to debug but x86 allmodconfig
is a very slow build on my laptop.

The static inline function declarations from the errors are in the else
case if an ifdef CONIG_MULTIPLEXER.

The mux.c should only be compiled if CONFIG_MULTIPLEXER is defined,
based on drivers/mux/Makefile:

mux-core-objs                   := core.o
obj-$(CONFIG_MULTIPLEXER)       += mux-core.o

I don't understand how it is possible for mux.c to be compiled,
while at the same time CONFIG_MULTIPLEXER is not defined.

Any ideas?
