Hi,

FYI, your patch has been queued to stable release 20.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/07/21. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/6b544c78a3819fa53ac52e97637567bd37ebf085

Thanks.

Subject: [PATCH] net/bnxt: release HWRM lock in error

[ upstream commit ec0a96819d35070276f350c2488203e7ab72aed4 ]

In __bnxt_hwrm_func_qcaps, when memory allocations fails
driver is not releasing the hwrm lock. This patch fixes it
by calling hwrm_unlock in that error case.

Fixes: b7778e8a1c00 ("net/bnxt: refactor to properly allocate resources for PF/VF")
