Subject: [PATCH 2/3] drm/amdgpu: remove unnecessary asic type check
Date: Wed, 9 Dec 2020 23:28:11 +0800	[thread overview]
Message-ID: <20201209152812.3215-2-Hawking.Zhang@amd.com> (raw)
In-Reply-To: <20201209152812.3215-1-Hawking.Zhang@amd.com>

The number of crtc should be 0 for ASICs that don't
have display engine. Remove the unnecessary asic type
check then.
