Subject: [PATCH v2] dmaengine: axi-dmac: Request IRQ with IRQF_SHARED
Date:   Thu, 26 Apr 2018 10:40:00 -0700
Message-Id: <20180426174000.12008-1-mdf@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Request IRQ with IRQF_SHARED flag. This works since the interrupt
handler already checks if there is an actual IRQ pending and returns
IRQ_NONE otherwise.
