Date: Tue, 25 Mar 2014 10:15:47 -0700 From: Kamal Mostafa <kamal@...onical.com> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, kernel-team@...ts.ubuntu.com Cc: Tomasz Nowicki <tomasz.nowicki@...aro.org>, "Rafael J. Wysocki" <rafael.j.wysocki@...el.com>, Kamal Mostafa <kamal@...onical.com> Subject: [PATCH 3.8 34/81] ACPI / PCI: Fix memory leak in acpi_pci_irq_enable() 3.8.13.20 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Tomasz Nowicki <tomasz.nowicki@...aro.org> commit b685f3b1744061aa9ad822548ba9c674de5be7c6 upstream. 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.
