This is a note to let you know that I've just added the patch titled
drm/radeon: Delay Connector detecting when HPD singals is unstableto the 6.6-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git%3Ba=su...
The filename of the patch is: drm-radeon-delay-connector-detecting-when-hpd-singal.patch and it can be found in the queue-6.6 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.

drm/radeon: Delay Connector detecting when HPD singals is unstable [ Upstream commit 949658cb9b69ab9d22a42a662b2fdc7085689ed8 ] In some causes, HPD signals will jitter when plugging in or unplugging HDMI. Rescheduling the hotplug work for a second when EDID may still be readable but HDP is disconnected, and fixes this issue.

Please drop both of these patches. There is no need to pull back a patch just so that you can apply the revert.
Since we've just been discussing stable backports at length, how did this one happen?
949658cb9b69ab9d22a42a662b2fdc7085689ed8 is in v6.11 and 979bfe291b5b in v6.13-rc1, so there's definitely a need to backport the latter to v6.11.y and v6.12.y. And maybe there was a cherry-pick of 949658cb9b69ab9d22a42a66 to older stable releases already, but that doesn't seem to be the case. So what happened here?
