From: Márton Németh <[email protected]> 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 <[email protected]> Cc: Julia Lawall <[email protected]> Cc: [email protected] --- diff -u -p a/drivers/usb/usb-skeleton.c b/drivers/usb/usb-skeleton.c --- a/drivers/usb/usb-skeleton.c 2010-01-07 19:08:47.000000000 +0100 +++ b/drivers/usb/usb-skeleton.c 2010-01-08 17:04:07.000000000 +0100 @@ -28,7 +28,7 @@ #define USB_SKEL_PRODUCT_ID 0xfff0 /* table of devices that work with this driver */ -static struct usb_device_id skel_table[] = { +static const struct usb_device_id skel_table[] = { { USB_DEVICE(USB_SKEL_VENDOR_ID, USB_SKEL_PRODUCT_ID) }, { } /* Terminating entry */ }; _______________________________________________ Cocci mailing list [email protected] http://lists.diku.dk/mailman/listinfo/cocci (Web access from inside DIKUs LAN only)
