Subject: [PATCH v3 02/14] irqchip/irq-bcm7038-l1: Remove .irq_cpu_offline()
Date: Tue, 28 Sep 2021 11:21:27 -0700 [thread overview]
Message-ID: <20210928182139.652896-3-f.fainelli@gmail.com> (raw)
In-Reply-To: <20210928182139.652896-1-f.fainelli@gmail.com>
With arch/mips/kernel/smp-bmips.c having been migrated away from
irq_cpu_offline() and use irq_migrate_all_off_this_cpu() instead, we no
longer need to implement an .irq_cpu_offline() callback. This is a
necessary change to facilitate the building of this driver as a module.
