Subject: [v2 net 04/12] net/mlx5: Fix error print in case of IRQ request failed
Date: Thu, 23 Dec 2021 11:04:33 -0800 [thread overview]
Message-ID: <20211223190441.153012-5-saeed@kernel.org> (raw)
In-Reply-To: <20211223190441.153012-1-saeed@kernel.org>
From: Shay Drory <shayd@nvidia.com>
In case IRQ layer failed to find or to request irq, the driver is
printing the first cpu of the provided affinity as part of the error
print. Empty affinity is a valid input for the IRQ layer, and it is
an error to call cpumask_first() on empty affinity.
Remove the first cpu print from the error message.
Fixes: c36326d38d93 ("net/mlx5: Round-Robin EQs over IRQs")
