[PATCH 5/5] drm/nouveau/drm: Bump the driver version to 1.4.1 to report new features
Wow, I think this might be the first time I've gotten to witness someone bump the DRM driver version! I think this is a fine reason to do so though. One change we should do though: we're going from 1.3.1 to 1.4.1 even though there's no 1.4.0. So, I think using 1.4.0 would probably be a better version (unless there's some explicit reason for the .1 that I'm not seeing here).

[PATCH 5/5] drm/nouveau/drm: Bump the driver version to 1.4.1 to report new features
Heyy, We're actually going from 1.4.0 to 1.4.1; it's just when the version bump was done to 1.4.0, it wasn't documented back then. 1.4.0 was VM_BIND so it was a pretty big change as well.
