From 577cdf0cf5afa5f350fbaddf77bbacdb9f76d2f8 Mon Sep 17 00:00:00 2001 From: Márton Németh Date: Sun, 10 Jan 2010 13:39:39 +0100 Subject: block: make USB device id constant MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The id_table field of the struct usb_device_id is constant in so it is worth to make ub_usb_ids 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: Jens Axboe --- drivers/block/ub.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/block/ub.c') diff --git a/drivers/block/ub.c b/drivers/block/ub.c index c739b203fe9..d86d1357cce 100644 --- a/drivers/block/ub.c +++ b/drivers/block/ub.c @@ -393,7 +393,7 @@ static int ub_probe_lun(struct ub_dev *sc, int lnum); #define ub_usb_ids usb_storage_usb_ids #else -static struct usb_device_id ub_usb_ids[] = { +static const struct usb_device_id ub_usb_ids[] = { { USB_INTERFACE_INFO(USB_CLASS_MASS_STORAGE, US_SC_SCSI, US_PR_BULK) }, { } }; -- cgit v1.2.3-18-g5258
