This commit has been processed because it contains a -stable tag. The stable tag indicates that it's relevant for the following trees: all

The bot has tested the following trees: v4.19.6, v4.14.85, v4.9.142, v4.4.166, v3.18.128,

v4.19.6: Build OK! v4.14.85: Failed to apply! Possible dependencies: cd414f3d9316 ("drm/msm: Move memptrs to msm_gpu") eec874ce5ff1 ("drm/msm/adreno: load gpu at probe/bind time") f7de15450e90 ("drm/msm: Add per-instance submit queues") f97decac5f4c ("drm/msm: Support multiple ringbuffers")

v4.14.85 can be rebased fairly cleanly:

https://gitlab.collabora.com/robertfoss/linux/commits/msm_in_fence_put_v3_v4...

However v4.9.142 and earlier does not rebase very cleanly at all. I don't know what the rule of thumb for backporting fixes is, but the feature that is fixed here does not seem to exist in v4.9.142 and earlier.

How should we proceed with this patch?
