You only create 1 issue and use it for backporting

oops. Thanks, @nordicjm! I'll keep this and close others for all backports.

BTW, do you have a pointer to a doc how to request backporting? search https://docs.zephyrproject.org/ but didn't find. All I found was https://github.com/zephyrproject-rtos/zephyr/wiki/Zephyr-Change-Control-Board-(CCB)

Seems not, all there is is https://docs.zephyrproject.org/latest/project/dev_env_and_tools.html

Backport
The PR is a backport or should be backported.

But essentially you create an issue without any labels, then on your main PR add the backport labels (either before or after it has been merged) then the bot will automatically create the backport PRs, if there are no merge conflicts then you just edit the bot's posts to have Fixes #<bug_id> and re-run the compliance check, if there are merge conflicts then you need to check out the specific branch that was created and fix them

Closing as it seems to be merged in all old branches
