Subject: [PATCH] drm/amd/display: fix unused variable warning
Date: Mon, 25 Jan 2021 13:48:43 +0100
Message-ID: <20210125124849.102037-1-arnd@kernel.org> (raw)

From: Arnd Bergmann <arnd@arndb.de>

After all users of the 'dm' warnings got hidden in an #ifdef,
the compiler started warning about it being unused:

drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:5380:33: error: unused variable 'dm' [-Werror,-Wunused-variable]

Add another such #ifdef.

Fixes: 98ab5f3513f9 ("drm/amd/display: Fix deadlock during gpu reset v3")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
