The backport of commit 9c5df2f14ee3 ("can: isotp: isotp_ops: fix poll() to not report false EPOLLOUT events") introduced a new regression where the fix could potentially introduce new side effects.
To reduce the risk of other unmet dependencies and missing fixes and checks the latest 6.1 LTS code base is ported back to the 5.15 LTS tree.
