Subject: [PATCH 12/15] irq: openrisc: perform irqentry in entry code
Date: Thu, 21 Oct 2021 19:02:33 +0100 [thread overview]
Message-ID: <20211021180236.37428-13-mark.rutland@arm.com> (raw)
In-Reply-To: <20211021180236.37428-1-mark.rutland@arm.com>
In preparation for removing HANDLE_DOMAIN_IRQ_IRQENTRY, have
arch/openrisc perform all the irqentry accounting in its entry code. As
arch/openrisc uses GENERIC_IRQ_MULTI_HANDLER, we can use
generic_handle_arch_irq() to do so.
There should be no functional change as a result of this patch.
