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/input/tablet/gtco.c b/drivers/input/tablet/gtco.c --- a/drivers/input/tablet/gtco.c 2009-12-03 04:51:21.000000000 +0100 +++ b/drivers/input/tablet/gtco.c 2010-01-08 19:11:02.000000000 +0100 @@ -92,7 +92,7 @@ Scott Hill [email protected] /* DATA STRUCTURES */ /* Device table */ -static struct usb_device_id gtco_usbid_table [] = { +static const struct usb_device_id gtco_usbid_table[] = { { USB_DEVICE(VENDOR_ID_GTCO, PID_400) }, { USB_DEVICE(VENDOR_ID_GTCO, PID_401) }, { USB_DEVICE(VENDOR_ID_GTCO, PID_1000) }, diff -u -p a/drivers/input/touchscreen/usbtouchscreen.c b/drivers/input/touchscreen/usbtouchscreen.c --- a/drivers/input/touchscreen/usbtouchscreen.c 2010-01-07 19:08:40.000000000 +0100 +++ b/drivers/input/touchscreen/usbtouchscreen.c 2010-01-08 19:17:10.000000000 +0100 @@ -144,7 +144,7 @@ enum { .bInterfaceClass = USB_INTERFACE_CLASS_HID, \ .bInterfaceProtocol = USB_INTERFACE_PROTOCOL_MOUSE -static struct usb_device_id usbtouch_devices[] = { +static const struct usb_device_id usbtouch_devices[] = { #ifdef CONFIG_TOUCHSCREEN_USB_EGALAX /* ignore the HID capable devices, handled by usbhid */ {USB_DEVICE_HID_CLASS(0x0eef, 0x0001), .driver_info = DEVTYPE_IGNORE}, _______________________________________________ Cocci mailing list [email protected] http://lists.diku.dk/mailman/listinfo/cocci (Web access from inside DIKUs LAN only)
