Subject: [PATCH] genirq/affinity: remove unused arg when building aff mask
Date: Sun, 2 Jun 2019 20:21:17 +0900 [thread overview]
Message-ID: <20190602112117.31839-1-minwoo.im.dev@gmail.com> (raw)
When building affinity masks, the struct irq_affinity *affd is not
needed because irq_create_affinity_masks() has already given a cursored
current vector after pre_vectors via "curvec".
This patch removes unused argument for irq_build_affinity_masks() and
__irq_build_affinity_masks(). No functions changes are included.
