patch 'net/sfc: remove null dereference in log' has been queued to stable release 22.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/13/23. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=28f7dd30ee751f439839811ffa99395f6503ccb0

Thanks.

Subject: [PATCH] net/sfc: remove null dereference in log
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit d05ce802f39dd4a67c18f9dbe1a00901429ba191 ]

When ctx->sa is null, sfc_err(ctx->sa, ...) will trigger a null
dereference in the macro of sfc_err. Use SFC_GENERIC_LOG(ERR, ...)
to avoid that.

Fixes: 44db08d53be3 ("net/sfc: maintain controller to EFX interface mapping")
