[git pull] drm fixes for 7.3-rc4
From: Dave Airlie
Date: Fri Sep 18 2026 - 18:17:23 EST
Hi Linus,
Things have picked back up a bit this week, mostly amdgpu, xe and msm
this time. There are a bunch of scattered changes across the rest of
drivers and core stuff, nouveau, i915.
In the signed tag I forgot to add the versilicon and longsoon entries,
but they are in the email below.
Regards,
Dave.
