From: Christian König Date: Wed, 18 Aug 2021 12:05:28 +0000 (+0200) Subject: drm/amdgpu: use the preferred pin domain after the check X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=2a7b9a8437130fd328001f4edfac8eec98dfe298;p=kernel.git drm/amdgpu: use the preferred pin domain after the check For some reason we run into an use case where a BO is already pinned into GTT, but should be pinned into VRAM|GTT again. Handle that case gracefully as well.
