Subject: [PATCH 18/23] KVM: arm64: Move set_owner into irqchip_flow
Date: Thu,  3 Sep 2020 16:26:05 +0100	[thread overview]
Message-ID: <20200903152610.1078827-19-maz@kernel.org> (raw)
In-Reply-To: <20200903152610.1078827-1-maz@kernel.org>

Move the set_owner callback into irqchip_flow. It's not that
useful an API anyway, and we should consider getting rid of it.
