Subject: [PATCH v2 6/8] common/mlx5: fix calloc parameters
Date: Wed, 24 Jan 2024 18:54:03 +0000	[thread overview]
Message-ID: <20240124185406.3598985-6-ferruh.yigit@amd.com> (raw)
In-Reply-To: <20240124185406.3598985-1-ferruh.yigit@amd.com>

gcc [1] generates warning [2] about calloc usage, because calloc
parameter order is wrong, fixing it by replacing parameters.

[1]
gcc (GCC) 14.0.1 20240124 (experimental)

[2]
Compiling C object .../common_mlx5_mlx5_common_mr.c.o
.../mlx5/mlx5_common_mr.c: In function ‘mlx5_mempool_get_chunks’:
.../common/mlx5/mlx5_common_mr.c:1384:29:
  warning: ‘calloc’ sizes specified with ‘sizeof’ in the earlier
  argument and not in the later argument [-Wcalloc-transposed-args]
 1384 |         *out = calloc(sizeof(**out), n);
      |                             ^
