Ugh, apologies, I didn't have a non-ACPI platform available to test
this on.

Solution is to either add to include/linux/acpi.h

static inline bool acpi_dev_present(const char *hid)
{
return false;
}

somewhere below

#else /* !CONFIG_ACPI */

or alternatively to add to include/linux/apple-gmux.h

IS_ENABLED(CONFIG_ACPI)

in apple_gmux_present().

I'll check the other users of acpi_dev_present() to see which of
these two solutions is more appropriate and will post a fix shortly.

Thanks a lot for reporting this.

Lukas
