Subject[PATCH][next] net/mlx4_core: fix incorrect size allocation for dev->caps.spec_qps
Date
From: Colin Ian King <colin.king@canonical.com>

The current allocation for dev->caps.spec_qps is for the size of the
pointer and not the size of the actual mlx4_spec_qps structure. Fix
this by using the correct size. Also splint allocation over a few
lines to make it cppcheck clean on overly wide lines.

Detected by CoverityScan, CID#1455222 ("Wrong sizeof argument")

Fixes: c73c8b1e47ca ("net/mlx4_core: Dynamically allocate structs at mlx4_slave_cap")
