The patch included below fixes the build if CONFIG_ACPI is not set.
@Daniel Vetter: Would it be possible to squash this with 2413306c2566
("apple-gmux: Add helper for presence detect") on topic/drm-misc so
as to avoid build breakage for anyone trying to bisect between that
commit and this fix?
I checked all other users of acpi_dev_present() and all of them are
only compiled if CONFIG_ACPI is set. Hence I opted to fix this in
<linux/apple-gmux.h> rather than in <linux/acpi.h>.
Thanks again Stephen for reporting this at such an early stage,
though doubtlessly it would have been better if I had thought of
this possibility when preparing the original patch, or if I had
compile-tested without CONFIG_ACPI. :-(

Subject: [PATCH] apple-gmux: Fix build breakage if !CONFIG_ACPI
The DRM drivers i915, nouveau and radeon may be compiled with
CONFIG_ACPI not set, in which case acpi_dev_present() is undefined.
Add a no-op stub for apple_gmux_present() which is used if
CONFIG_APPLE_GMUX is not enabled to avoid build breakage.
(CONFIG_APPLE_GMUX depends on CONFIG_ACPI.)
