From f9dd0ce67db80079484f154a27581e30c28e6938 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 9 Sep 2014 15:11:50 +0300 Subject: [PATCH] PCI: xilinx: Fix xilinx_pcie_assign_msi() return value test We should be testing "hwirq" instead of "irq". "irq" is unsigned so it's never less than zero. Also it's uninitialized.
