Message-Id: <1451991431-8342-1-git-send-email-colin.king@canonical.com> Date: Tue, 5 Jan 2016 10:57:11 +0000 From: Colin King <colin.king@...onical.com> To: "Rafael J . Wysocki" <rafael.j.wysocki@...el.com>, Len Brown <len.brown@...el.com>, linux-acpi@...r.kernel.org Cc: linux-kernel@...r.kernel.org Subject: [PATCH] ACPI, PCI, irq: remove redundant check for null string pointer From: Colin Ian King <colin.king@...onical.com> 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.
