patch 'vdpa/sfc: fix null dereference during removal' has been queued to stable release 21.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/26/22. 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://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/8f821b11356db2d496b09a2540e623ef6938c993

Thanks.

Kevin

Subject: [PATCH] vdpa/sfc: fix null dereference during removal

[ upstream commit 500640b328c2ce623715ca8ec013e7a8ff922428 ]

When sva is null, sfc_vdpa_info(sva, ...) will cause a null
dereference. Use SFC_VDPA_GENERIC_LOG() to avoid that.
See macros sfc_vdpa_info and SFC_VDPA_GENERIC_LOG
defined in drivers/vdpa/sfc/sfc_vdpa_log.h for detail.

Fixes: 5e7596ba7cb3 ("vdpa/sfc: introduce Xilinx vDPA driver")
