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/usb/core/hub.c b/drivers/usb/core/hub.c --- a/drivers/usb/core/hub.c 2010-01-07 19:08:47.000000000 +0100 +++ b/drivers/usb/core/hub.c 2010-01-08 17:20:19.000000000 +0100 @@ -3442,7 +3442,7 @@ static int hub_thread(void *__unused) return 0; } -static struct usb_device_id hub_id_table [] = { +static const struct usb_device_id hub_id_table[] = { { .match_flags = USB_DEVICE_ID_MATCH_DEV_CLASS, .bDeviceClass = USB_CLASS_HUB}, { .match_flags = USB_DEVICE_ID_MATCH_INT_CLASS, -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
