Subject: [PATCH 1/3] drm/i915: rename IS_ACTIVE
Date:   Wed, 29 Sep 2021 11:16:30 -0700

It took me some time to understand the need for IS_ACTIVE and why we
couldn't use kconfig.h. Rename it to something else that would be more
suitable to include in kconfig.h and shared with other subsystems rather
than maintaining it only in i915.

Name here is pretty open for suggestions, but I think this is slightly
better than "active".
