Subject: drm/ttm/tests: depend on UML || COMPILE_TEST
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9d3f8a723c7950e56e0b95ab84b572caee29e065;p=linux.git

drm/ttm/tests: depend on UML || COMPILE_TEST

At least the device test requires that no other driver using TTM is
loaded. So make those unit tests depend on UML || COMPILE_TEST to
prevent people from trying them on bare metal.
