From 45288978859119c019eff93f0cb838a0de100bcc Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Tue, 5 Jan 2016 10:57:11 +0000 Subject: [PATCH] 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 Signed-off-by: Rafael J.
