From c97adf9e7bebf17a86b95e2131bf9ba76c4857c7 Mon Sep 17 00:00:00 2001 From: Márton Németh Date: Sun, 10 Jan 2010 17:15:36 +0100 Subject: acpi: make ACPI device id constant MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The ids field of the struct acpi_driver is constant in so it is worth to make the initialization data also constant. The semantic match that finds this kind of pattern is as follows: (http://coccinelle.lip6.fr/) // @r@ disable decl_init,const_decl_init; identifier I1, I2, x; @@ struct I1 { ... const struct I2 *x; ... }; @s@ identifier r.I1, y; identifier r.x, E; @@ struct I1 y = { .x = E, }; @c@ identifier r.I2; identifier s.E; @@ const struct I2 E[] = ... ; @depends on !c@ identifier r.I2; identifier s.E; @@ + const struct I2 E[] = ...; // Signed-off-by: Márton Németh Cc: Julia Lawall Cc: cocci@diku.dk Signed-off-by: Len Brown --- drivers/acpi/pci_link.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/acpi/pci_link.c') diff --git a/drivers/acpi/pci_link.c b/drivers/acpi/pci_link.c index 394ae89409c2..04b0f007c9b7 100644 --- a/drivers/acpi/pci_link.c +++ b/drivers/acpi/pci_link.c @@ -56,7 +56,7 @@ ACPI_MODULE_NAME("pci_link"); static int acpi_pci_link_add(struct acpi_device *device); static int acpi_pci_link_remove(struct acpi_device *device, int type); -static struct acpi_device_id link_device_ids[] = { +static const struct acpi_device_id link_device_ids[] = { {"PNP0C0F", 0}, {"", 0}, }; -- cgit v1.2.3
