From: Victor Zhao Date: Thu, 13 Oct 2022 03:06:33 +0000 (+0800) Subject: Revert "drm/amdgpu: let mode2 reset fallback to default when failure" X-Git-Tag: v6.6.17~6326^2~2^2~22 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a340847b0214aa9b8fd9839f7b2822ccc607edab;p=platform%2Fkernel%2Flinux-rpi.git Revert "drm/amdgpu: let mode2 reset fallback to default when failure" This reverts commit dac6b80818ac2353631c5a33d140d8d5508e2957. This commit reverted the AMDGPU_SKIP_MODE2_RESET as it conflicts with the original design of reset handler. Will redesign it.
