Control: tags -1 + fixed-upstream

The patch attached to this report was merged upstream (drm-misc-fixes branch)
as
https://cgit.freedesktop.org/drm/drm-misc/commit/drivers/gpu/drm/vc4?h=drm-misc-fixes&id=f6b57101a6b31277a4bde1d8028c46e898bd2ff2

This seems to satisfy the condition for Debian kernel patch
at
https://kernel-team.pages.debian.net/kernel-handbook/ch-bugs.html#s9.1.7

> 9.1.7. Applying patches
> Patches should normally be reviewed and accepted by the relevant upstream maintainer
> (aside from necessary adjustments for an older kernel version) before being applied.
