[PATCH 5.15 060/110] net: ieee802154: Return meaningful error codes from the netlink helpers

From: Greg Kroah-Hartman
Date: Mon Feb 07 2022 - 06:48:50 EST


From: Miquel Raynal <miquel.raynal@xxxxxxxxxxx>

commit 79c37ca73a6e9a33f7b2b7783ba6af07a448c8a9 upstream.

Returning -1 does not indicate anything useful.

Use a standard and meaningful error code instead.

Fixes: a26c5fd7622d ("nl802154: add support for security layer")
