ACPI, PCI, irq: remove redundant check for null string pointer
source is decleared as a 4 byte char array in struct acpi_pci_routing_table so !prt->source is a redundant null string pointer check. Detected with smatch: drivers/acpi/pci_irq.c:134 do_prt_fixups() warn: this array is probably non-NULL. 'prt->source' Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
