[PATCH 2/2] IB/mlx5: Fix existence check for extended address vector
From: Leon Romanovsky <leon@kernel.org>
Date: 2017-06-12 07:36:23
Also in:
stable
Subsystem:
infiniband subsystem, mellanox mlx5 ib driver, mellanox mlx5 core vpi driver, the rest · Maintainers:

From: Leon Romanovsky <redacted>
The extended address vector is the highest bit in be32 variable,
but it was compared with the lowest. This patch fixes the endianness
of that check and removes already declared define.
Fixes: 17d2f88f92ce ("IB/mlx5: Add ODP atomics support")
