In-Reply-To: <1472553558-27215-1-git-send-email-bharatku@xilinx.com> References: <1472553558-27215-1-git-send-email-bharatku@xilinx.com> Message-ID: <1472553558-27215-3-git-send-email-bharatku@xilinx.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org PCIe legacy interrupts start at 1, not at 0. When testing with multi function device "error: hwirq 0x4 is too large for dummy" error comes. So adding one addtional interrupt when creating irq domain.
