Re: [PATCH] drm/panfrost: Rename "panthor" prefixes in debugfs identifiers

[Adrián Larumbe]

Hi Nicolas, thanks for the patch.

I was wondering whether it makes sense to apply it in light of changes
in a patch series I've been working on for quite some time. One of the
patches moves all debugfs plumbing away from panfrost_drv.c and into
their relevant subsystems, and as part of that change I've renamed all
erroneous panthor_* prefixes into panfrost.

However, if the right policy in this case is to have them both committed
separately, then I'll be applying this one first.

Check https://lore.kernel.org/r/20260912-claude-fixes-v9-0-e588feaa61ef@xxxxxxxxxxxxx
patch 3/16 for further context.
