Subject: [net-next V2 12/16] net/mlx5: Fix bit-wise and with zero
Date: Wed, 14 Apr 2021 11:06:01 -0700	[thread overview]
Message-ID: <20210414180605.111070-13-saeed@kernel.org> (raw)
In-Reply-To: <20210414180605.111070-1-saeed@kernel.org>

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

The bit-wise and of the action field with MLX5_ACCEL_ESP_ACTION_DECRYPT
is incorrect as MLX5_ACCEL_ESP_ACTION_DECRYPT is zero and not intended
to be a bit-flag. Fix this by using the == operator as was originally
intended.

Addresses-Coverity: ("Logically dead code")
Fixes: 7dfee4b1d79e ("net/mlx5: IPsec, Refactor SA handle creation and destruction")
