I building module with custom kernel 4.14.22 and get the errors:

make: Entering directory '/home/gay/linux-4.14.22'

Here is my kernel .config file.

I found that APPLE_GMUX=m is required. Fixed now.

I think your problem was actually that you didn't have ACPI=y - enabling APPLE_GMUX has the side effect of also enabling ACPI.

zhovner commented 6 years ago

You can look at .config file to see that CONFIG_ACPI=y is enabled.
