Bug Description
[Impact]
System stuck at boot when Intel 7560 is in use, because devlink
is waiting for reference to be released.
[Fix]
Commit "devlink: remove the registration guarantee of references"
weakens the refcount requirement for devlink {,un}registering,
[Test]
System reboots over 2000 times when the fix is applied.
[Where problems could occur]
devlink is part of net core API, so it has many users, therefore all of
devlink users can be affected by this fix. However, all the devlink
users can be affected by the same issue (i.e. waiting for reference to
decrease to 0), hence this is still a desirable fix.

Is all of this included in 6.5? Even if so, it would be nice to have the 'linux' tab opened and marked fix-released so that it's clear for the reviewer.
