Subject: [PATCH v2 08/17] can: netlink: can_changelink(): convert from netdev_err() to NL_SET_ERR_MSG_FMT()
Date: Thu, 2 Feb 2023 12:08:45 +0100 [thread overview]
Message-ID: <20230202110854.2318594-9-mkl@pengutronix.de> (raw)
In-Reply-To: <20230202110854.2318594-1-mkl@pengutronix.de>
Since commit 51c352bdbcd2 ("netlink: add support for formatted extack
messages") formatted extack messages are supported to inform the user
space or warnings/errors during netlink calls.
Replace the netdev_err() by NL_SET_ERR_MSG_FMT() to better inform the
user about the problem. While there, use %u to print unsigned values
and improve error message a bit.
