SLPC unset param H2G only needs one parameter - the id of the

How serious is this? Does it need backporting? If so:
Cc: <stable@xxxxxxxxxxxxxxx> # v5.15+
?
This path (unset_param) is not being exercised currently, so not very
serious.
Got it, and looking at the code it seems to hold - no possible entry to
the path at the moment.
Note for the future - this is useful stuff to put in commit messages,
especially when Fixes: is present. ;)
