[PATCH] drm: Drop ARCH_MULTIPLATFORM from dependencies

[PATCH] drm: Drop ARCH_MULTIPLATFORM from dependencies

[Uwe Kleine-König]

Some of these dependencies used to be sensible when only a small part of
the platforms supported by ARCH=arm could be compiled together in a
single kernel image. Nowadays ARCH_MULTIPLATFORM is only used as a guard
for kernel options incompatible with a multiplatform image. See commit
84fc86360623 ("ARM: make ARCH_MULTIPLATFORM user-visible") for some more
details.

Since the original purpose of the ||ARCH_MULTIPLATFORM was to allow
building the driver on more targets, I wonder if we should instead
make that ||COMPILE_TEST, which would also allow building it on
x86 and others.

Thanks. (But honestly I'm not surprised you agree to this patch after
our conversation on irc :-)

I wondered about that, too, but thought that would be a new patch.

This makes sense to me as well, but it would be great if someone else
from DRM can review/ack before pushing it.

Agreed that making it || COMPILE_TEST should be in a separate patch.
