In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Return the firmware result upon destroying QP/RQ Previously when destroying a QP/RQ, the result of the firmware destruction function was ignored and upper layers weren't informed about the failure. Which in turn could lead to various problems since when upper layer isn't aware of the failure it continues its operation thinking that the related QP/RQ was successfully destroyed while it actually wasn't, which could lead to the below kernel WARN. Currently, we return the correct firmware destruction status to upper lay
