drm/panthor: Report innocent group kill
Groups can be killed during a reset even though they did nothing wrong.
That usually happens when the FW is put in a bad state by other groups,
resulting in group suspension failures when the reset happens.
If we end up in that situation, flag the group innocent and report
innocence through a new DRM_PANTHOR_GROUP_STATE flag.
Bump the minor driver version to reflect the uAPI change.
Changes in v4:
- Add an entry to the driver version changelog
- Add R-bs
Changes in v3:
- Actually report innocence to userspace
Changes in v2:
- New patch
