From f0b507774449ec35fbfd7173e5fc7dd4df71a81c Mon Sep 17 00:00:00 2001 From: Chao Xie Date: Mon, 27 Jan 2014 09:44:07 +0800 Subject: [PATCH] dma: mmp_pdma: add IRQF_SHARED when request irq For some SOCes use mmp_pdma, they have several dma controllers sharing same irq. So add IRQF_SHARED to flag when request irq. It can make multiple controllers share the same irq.
