Subject: [net-next 05/15] net/mlx5: IRQ, consolidate irq and affinity mask allocation
Date: Wed, 16 Aug 2023 14:00:39 -0700 [thread overview]
Message-ID: <20230816210049.54733-6-saeed@kernel.org> (raw)
In-Reply-To: <20230816210049.54733-1-saeed@kernel.org>
From: Saeed Mahameed <saeedm@nvidia.com>
Consolidate the mlx5_irq and mlx5_irq->mask allocation, to simplify
error flows and to match the dealloctation sequence @irq_release for
symmetry.
