Sat Dec 3 10:22:55 UTC 2022


Commit 399516ab0fee ("MAINTAINERS: Add a bunch of legacy (UMS) DRM drivers")
marked savage driver obsolete 7 years ago.
And the mesa UMD of this drm driver already in deprecated list
in the link: https://docs.mesa3d.org/systems.html
S3 Savage-->drivers/gpu/drm/savage

It's time to remove this driver.
