[PATCH 5.14 063/151] net/mlx5: Fix length of irq_index in chars

[Greg Kroah-Hartman]

From: Shay Drory <shayd@xxxxxxxxxx>

[ Upstream commit ac8b7d50ae4c3f5325c599f3d6e939ecef6a585a ]

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")
