Add const to the declaration of various local variables of type kempld_platform_data for which the referenced value is always only dereferenced or passed to a const parameter, to record the fact that kempld_platform_data_generic is declared as const. The semantic match that finds this issue is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier i,j; @@ const struct i j = { ... }; @ok@ identifier r.i; position p; @@ const struct i@p * @@ identifier r.i; position p != ok.p; @@ * struct i@p * // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- drivers/mfd/kempld-core.c | 15 ++++++++------- 1 file changed, 8 insertions(+), 7 deletions(-) diff --git a/drivers/mfd/kempld-core.c b/drivers/mfd/kempld-core.c index 390b27c..fb5a10b 100644 --- a/drivers/mfd/kempld-core.c +++ b/drivers/mfd/kempld-core.c @@ -143,7 +143,7 @@ static int kempld_register_cells_generic(struct kempld_device_data *pld) static int kempld_create_platform_device(const struct dmi_system_id *id) { - struct kempld_platform_data *pdata = id->driver_data; + const struct kempld_platform_data *pdata = id->driver_data; int ret; kempld_pdev = platform_device_alloc("kempld", -1); @@ -259,7 +259,7 @@ void kempld_write32(struct kempld_device_data *pld, u8 index, u32 data) */ void kempld_get_mutex(struct kempld_device_data *pld) { - struct kempld_platform_data *pdata = dev_get_platdata(pld->dev); + const struct kempld_platform_data *pdata = dev_get_platdata(pld->dev); mutex_lock(&pld->lock); pdata->get_hardware_mutex(pld); @@ -272,7 +272,7 @@ void kempld_get_mutex(struct kempld_device_data *pld) */ void kempld_release_mutex(struct kempld_device_data *pld) { - struct kempld_platform_data *pdata = dev_get_platdata(pld->dev); + const struct kempld_platform_data *pdata = dev_get_platdata(pld->dev); pdata->release_hardware_mutex(pld); mutex_unlock(&pld->lock); @@ -290,7 +290,7 @@ void kempld_release_mutex(struct kempld_device_data *pld) static int kempld_get_info(struct kempld_device_data *pld) { int ret; - struct kempld_platform_data *pdata = dev_get_platdata(pld->dev); + const struct kempld_platform_data *pdata = dev_get_platdata(pld->dev); char major, minor; ret = pdata->get_info(pld); @@ -332,7 +332,7 @@ static int kempld_get_info(struct kempld_device_data *pld) */ static int kempld_register_cells(struct kempld_device_data *pld) { - struct kempld_platform_data *pdata = dev_get_platdata(pld->dev); + const struct kempld_platform_data *pdata = dev_get_platdata(pld->dev); return pdata->register_cells(pld); } @@ -444,7 +444,8 @@ static int kempld_detect_device(struct kempld_device_data *pld) static int kempld_probe(struct platform_device *pdev) { - struct kempld_platform_data *pdata = dev_get_platdata(&pdev->dev); + const struct kempld_platform_data *pdata = + dev_get_platdata(&pdev->dev); struct device *dev = &pdev->dev; struct kempld_device_data *pld; struct resource *ioport; @@ -476,7 +477,7 @@ static int kempld_probe(struct platform_device *pdev) static int kempld_remove(struct platform_device *pdev) { struct kempld_device_data *pld = platform_get_drvdata(pdev); - struct kempld_platform_data *pdata = dev_get_platdata(pld->dev); + const struct kempld_platform_data *pdata = dev_get_platdata(pld->dev); sysfs_remove_group(&pld->dev->kobj, &pld_attr_group); -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
