Subject: [wpan v3 5/6] net: ieee802154: Return meaningful error codes from the netlink helpers
Date: Tue, 25 Jan 2022 13:14:25 +0100	[thread overview]
Message-ID: <20220125121426.848337-6-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20220125121426.848337-1-miquel.raynal@bootlin.com>

Returning -1 does not indicate anything useful.

Use a standard and meaningful error code instead.

Fixes: a26c5fd7622d ("nl802154: add support for security layer")
Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
