From 631e61b7ca12ef14c834f99f8948e410c539f585 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?M=C3=A1rton=20N=C3=A9meth?= 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/mpc52xx_psc_spi.c | 2 +- drivers/spi/mpc52xx_spi.c | 2 +- drivers/spi/spi_ppc4xx.c | 2 +- drivers/spi/xilinx_spi_of.c | 2 +- 4 files changed, 4 insertions(+), 4 deletions(-) (limited to 'drivers') diff --git a/drivers/spi/mpc52xx_psc_spi.c b/drivers/spi/mpc52xx_psc_spi.c index f50c81df336a..04747868d6c4 100644 --- a/drivers/spi/mpc52xx_psc_spi.c +++ b/drivers/spi/mpc52xx_psc_spi.c @@ -503,7 +503,7 @@ static int __exit mpc52xx_psc_spi_of_remove(struct of_device *op) return mpc52xx_psc_spi_do_remove(&op->dev); } -static struct of_device_id mpc52xx_psc_spi_of_match[] = { +static const struct of_device_id mpc52xx_psc_spi_of_match[] = { { .compatible = "fsl,mpc5200-psc-spi", }, { .compatible = "mpc5200-psc-spi", }, /* old */ {} diff --git a/drivers/spi/mpc52xx_spi.c b/drivers/spi/mpc52xx_spi.c index 45bfe6458173..6eab46537a0a 100644 --- a/drivers/spi/mpc52xx_spi.c +++ b/drivers/spi/mpc52xx_spi.c @@ -550,7 +550,7 @@ static int __devexit mpc52xx_spi_remove(struct of_device *op) return 0; } -static struct of_device_id mpc52xx_spi_match[] __devinitdata = { +static const struct of_device_id mpc52xx_spi_match[] __devinitconst = { { .compatible = "fsl,mpc5200-spi", }, {} }; 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", }, {}, }; diff --git a/drivers/spi/xilinx_spi_of.c b/drivers/spi/xilinx_spi_of.c index 71dc3adc0495..ed34a8d419c7 100644 --- a/drivers/spi/xilinx_spi_of.c +++ b/drivers/spi/xilinx_spi_of.c @@ -99,7 +99,7 @@ static int __exit xilinx_spi_of_remove(struct of_device *op) return xilinx_spi_remove(op); } -static struct of_device_id xilinx_spi_of_match[] = { +static const struct of_device_id xilinx_spi_of_match[] = { { .compatible = "xlnx,xps-spi-2.00.a", }, { .compatible = "xlnx,xps-spi-2.00.b", }, {} -- cgit v1.2.3
