Subject: [PATCH 2956/4131] drm/amdgpu: drop scratch regs save and restore from
GPU reset handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The expectation is that the base driver doesn't mess with these.
Some components interact with these directly so let the components
handle these directly.
