Merge tag 'drm-msm-fixes-2023-01-16' of https://gitlab.freedesktop.org/drm/msm into drm-fixes
msm-fixes for v6.3-rc5
Two GPU fixes which were meant to be part of the previous pull request,
but I'd forgotten to fetch from gitlab after the MR was merged so that
git tag was applied to the wrong commit.
- kexec shutdown fix
- fix potential double free
