Subject: [PATCH V4 1/6] genirq/affinity: Remove the 'firstvec' parameter from irq_build_affinity_masks
Date:   Tue, 27 Dec 2022 10:29:00 +0800
Message-Id: <20221227022905.352674-2-ming.lei@redhat.com>
In-Reply-To: <20221227022905.352674-1-ming.lei@redhat.com>

Precedence: bulk

The 'firstvec' parameter is always same with the parameter of
'startvec', so use 'startvec' directly inside irq_build_affinity_masks().
