From b701c0b1fe819a2083fc6ec5332e0e4492b9516d Mon Sep 17 00:00:00 2001 From: Alexei Starovoitov Date: Wed, 4 Jun 2014 15:49:50 -0700 Subject: [PATCH] PCI/MSI: Fix memory leak in free_msi_irqs() free_msi_irqs() is leaking memory, since list_for_each_entry(entry, &dev->msi_list, list) {...} is never executed, because dev->msi_list is made empty by the loop just above this one. Fix it by relying on zero termination of attribute array like populate_msi_sysfs() does.
