Subject: [PATCH][next] RDMA/mlx5: Fix missing assignment of rc when calling mlx5_ib_dereg_mr
Date: Tue, 16 Mar 2021 09:51:17 +0000	[thread overview]
Message-ID: <20210316095117.17089-1-colin.king@canonical.com> (raw)

From: Colin Ian King <colin.king@canonical.com>

The assignment of the return code to rc when calling mlx5_ib_dereg_mr is
missing and there is an error check on an uninitialized rc. Fix this by
adding in the assignment.

Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: e6fb246ccafb ("RDMA/mlx5: Consolidate MR destruction to mlx5_ib_dereg_mr()")
