Subject: [net 07/10] net/mlx5: Fix length of irq_index in chars
Date: Thu, 30 Sep 2021 16:14:58 -0700 [thread overview]
Message-ID: <20210930231501.39062-8-saeed@kernel.org> (raw)
In-Reply-To: <20210930231501.39062-1-saeed@kernel.org>
From: Shay Drory <shayd@nvidia.com>
The maximum irq_index can be 2047, This means irq_name should have 4
characters reserve for the irq_index. Hence, increase it to 4.
Fixes: 3af26495a247 ("net/mlx5: Enlarge interrupt field in CREATE_EQ")
