From 631e61b7ca12ef14c834f99f8948e410c539f585 Mon Sep 17 00:00:00 2001 From: Márton Németh Date: Wed, 20 Jan 2010 13:49:44 -0700 Subject: spi: make Open Firmware device id constant MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The match_table field of the struct of_device_id is constant in so it is worth to make the initialization data 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: Grant Likely --- drivers/spi/spi_ppc4xx.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/spi/spi_ppc4xx.c') diff --git a/drivers/spi/spi_ppc4xx.c b/drivers/spi/spi_ppc4xx.c index 140a18d6cf3e..6d8d4026a07a 100644 --- a/drivers/spi/spi_ppc4xx.c +++ b/drivers/spi/spi_ppc4xx.c @@ -578,7 +578,7 @@ static int __exit spi_ppc4xx_of_remove(struct of_device *op) return 0; } -static struct of_device_id spi_ppc4xx_of_match[] = { +static const struct of_device_id spi_ppc4xx_of_match[] = { { .compatible = "ibm,ppc4xx-spi", }, {}, }; -- cgit v1.2.3
