From b685f3b1744061aa9ad822548ba9c674de5be7c6 Mon Sep 17 00:00:00 2001 From: Tomasz Nowicki Date: Mon, 10 Feb 2014 14:00:11 +0100 Subject: [PATCH] ACPI / PCI: Fix memory leak in acpi_pci_irq_enable() acpi_pci_link_allocate_irq() can return negative gsi even if entry != NULL. For that case we have a memory leak, so free entry before returning from acpi_pci_irq_enable() for gsi < 0.
