| Subject: ACPI / PCI: Fix memory leak in acpi_pci_irq_enable() |
| |
| From: Tomasz Nowicki <tomasz.nowicki@linaro.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. |
