Overall I think these look reasonable. Partly updates to sauce patches,
which look reasonable to me, and a new driver which should not cause
regressions for already supported hardware. For bionic and cosmic:

However, your patches don't apply to disco/master-next or
unstable/master. Can you please supply patches for these trees? Thanks!
