From 8a11da598e2ff96050a99e24772e1568e3e31c4d Mon Sep 17 00:00:00 2001 From: Zubair Lutfullah Kakakhel Date: Mon, 14 Nov 2016 12:13:50 +0000 Subject: [PATCH] irqchip/xilinx: Try to fall back if xlnx,kind-of-intr not provided The powerpc dts file does not have the xlnx,kind-of-intr property. Instead of erroring out, give a warning instead. And attempt to continue to probe the interrupt controller while assuming kind-of-intr is 0x0 as a fall back.
