Unfortunately, it seems that this selection of only one update step
from this small patch series has got unwanted consequences.

Will the update suggestion “[patch] drm/savage: dereferencing an error pointer”
by Dan Carpenter (from today) trigger further software development discussions?

https://patchwork.kernel.org/patch/9372127/
https://lkml.kernel.org/r/<20161012062227.GU12841@...nda>

Will an update step like “[PATCH 2/2] GPU-DRM-Savage: Less function calls in
savage_bci_cmdbuf() after error detection” (from 2016-08-18) become worth
for related consideratons once more?
