From: Márton Németh <nm127@xxxxxxxxxxx> The id_table field of the struct usb_device_id is constant in <linux/usb.h> 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/) // <smpl> @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[] = ...; // </smpl> Signed-off-by: Márton Németh <nm127@xxxxxxxxxxx> Cc: Julia Lawall <julia@xxxxxxx> Cc: cocci@xxxxxxx --- diff -u -p a/drivers/hid/usbhid/hid-core.c b/drivers/hid/usbhid/hid-core.c --- a/drivers/hid/usbhid/hid-core.c 2010-01-07 19:08:40.000000000 +0100 +++ b/drivers/hid/usbhid/hid-core.c 2010-01-08 18:55:16.000000000 +0100 @@ -1342,7 +1342,7 @@ static int hid_reset_resume(struct usb_i #endif /* CONFIG_PM */ -static struct usb_device_id hid_usb_ids [] = { +static const struct usb_device_id hid_usb_ids[] = { { .match_flags = USB_DEVICE_ID_MATCH_INT_CLASS, .bInterfaceClass = USB_INTERFACE_CLASS_HID }, { } /* Terminating entry */ -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
