Subject: [PATCH V3 1/7] genirq/affinity: remove the 'firstvec' parameter from irq_build_affinity_masks
Date: Tue, 28 Sep 2021 08:55:52 +0800 [thread overview]
Message-ID: <20210928005558.243352-2-ming.lei@redhat.com> (raw)
In-Reply-To: <20210928005558.243352-1-ming.lei@redhat.com>
The 'firstvec' parameter is always same with the parameter of
'startvec', so use 'startvec' directly inside irq_build_affinity_masks().
