Subject: [PATCH 15/26] drm/amdgpu: use dma_resv_for_each_fence for CS workaround
Date: Tue, 23 Nov 2021 15:21:00 +0100	[thread overview]
Message-ID: <20211123142111.3885-16-christian.koenig@amd.com> (raw)
In-Reply-To: <20211123142111.3885-1-christian.koenig@amd.com>

Get the write fence using dma_resv_for_each_fence instead of accessing
it manually.
