Yeah we use Fixes: a lot, also to help all our product teams, who have all
varying versions of frankenstein kernels. If they cherry-pick some feature
from upstream, they need to know which bugfixes to backport. cc: stable is
orthogonal to Fixes:, but Fixes should imo indicate a real bugfix (i.e. if
you have the first patch, you want all the patches with Fixes: lines
referencing that patch).

Unfortunately on the mobile/gfx side there's very few customers who just
use a stable release, so we need to be rather dutiful with sprinkling
Fixes: tags over everything that fixes bugs (but not more, otherwise
there's screaming about backporting too much).
