Subject: [net 07/12] net/mlx5: Fix order of functions in mlx5_irq_detach_nb()
Date: Mon,  9 Aug 2021 20:59:18 -0700	[thread overview]
Message-ID: <20210810035923.345745-8-saeed@kernel.org> (raw)
In-Reply-To: <20210810035923.345745-1-saeed@kernel.org>

From: Shay Drory <shayd@nvidia.com>

Change order of functions in mlx5_irq_detach_nb() so it will be
a mirror of mlx5_irq_attach_nb.

Fixes: 71e084e26414 ("net/mlx5: Allocating a pool of MSI-X vectors for SFs")
