Hi,
Just checking, has anyone got this in a pull?
Dmitry's review was at the end of October.
(There's also a few others that Dmitry was kind enough to review
still outstanding:
drm: encoder_slave: Remove unused encoder functions
and
gpu: ipu-v3: Remove unused functions
)
(There's also drm/i915/gvt: Remove intel_gvt_ggtt_h2g<->index
and co that I've seen in Next but not in a pull yet)
Thanks,
Dave
