Lorenzo Pieralisi 8e3f3c06be ACPI/IORT: Fix iort_get_platform_device_domain() uninitialized pointer value ... [ Upstream commit ea2412dc21 ] Running the Clang static analyzer on IORT code detected the following error: Logic error: Branch condition evaluates to a garbage value in iort_get_platform_device_domain() If the named component associated with a given device has no IORT mappings, iort_get_platform_device_domain() exits its MSI mapping loop with msi_parent pointer containing garbage, which can lead to erroneous code path execution. Initialize the msi_parent pointer, fixing the bug.
