Subject: [PATCH 1/3] drm: Avoid circular dependencies for CONFIG_FB
Date: Wed,  2 Jun 2021 14:52:50 -0700	[thread overview]
Message-ID: <20210602215252.695994-2-keescook@chromium.org> (raw)
In-Reply-To: <20210602215252.695994-1-keescook@chromium.org>

When cleaning up other drm config dependencies, it is too easy to create
larger problems. Instead, mark CONFIG_FB as a "depends":

drivers/gpu/drm/Kconfig:74:error: recursive dependency detected!
