From 4b1cf1facca31b7db2a61d8aa2ba40d5a93a0957 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?M=C3=A1rton=20N=C3=A9meth?= Date: Tue, 2 Feb 2010 23:41:06 -0700 Subject: dma: 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 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 [dan.j.williams@intel.com: resolved conflict with recent fsldma updates] Signed-off-by: Dan Williams --- drivers/dma/fsldma.c | 2 +- drivers/dma/ppc4xx/adma.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) (limited to 'drivers') diff --git a/drivers/dma/fsldma.c b/drivers/dma/fsldma.c index 19011c20390b..92efa87258b9 100644 --- a/drivers/dma/fsldma.c +++ b/drivers/dma/fsldma.c @@ -1398,7 +1398,7 @@ static int fsldma_of_remove(struct of_device *op) return 0; } -static struct of_device_id fsldma_of_ids[] = { +static const struct of_device_id fsldma_of_ids[] = { { .compatible = "fsl,eloplus-dma", }, { .compatible = "fsl,elo-dma", }, {} diff --git a/drivers/dma/ppc4xx/adma.c b/drivers/dma/ppc4xx/adma.c index 0a3478e910f0..e69d87f24a25 100644 --- a/drivers/dma/ppc4xx/adma.c +++ b/drivers/dma/ppc4xx/adma.c @@ -4940,7 +4940,7 @@ out_free: return ret; } -static struct of_device_id __devinitdata ppc440spe_adma_of_match[] = { +static const struct of_device_id ppc440spe_adma_of_match[] __devinitconst = { { .compatible = "ibm,dma-440spe", }, { .compatible = "amcc,xor-accelerator", }, {}, -- cgit v1.2.2
