Subject: [ PATCH V2 2/7] dmaengine: change the flags of request_irq()
Date: Fri, 25 Mar 2011 18:22:56 +0800 [thread overview]
Message-ID: <1301048581-21321-3-git-send-email-b32955@freescale.com> (raw)
In-Reply-To: <1301048581-21321-1-git-send-email-b32955@freescale.com>
The GPMI may have many DMA channels, such as the imx23 has
four DMA channels. All these DMA channels share the same interrupt.
So change the flags from '0' to IRQF_SHARED, else there will be
an EBUSY error returns.
