From 8116acce5a7aba90d97170d04d4b497afa1b74cf Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Thu, 28 Jul 2016 16:16:18 +0000 Subject: [PATCH] PCI: keystone: Propagate request_irq() failure Previously, if request_irq() failed, ks_add_pcie_port() always returned zero (success). Return the request_irq() failure result instead.
