The file contains eg { PCI_VDEVICE(INTEL, 0x0800), (kernel_ulong_t)&spi_pci_mid_desc_1} which Coccinelle was incorrectly interpreting as a bit and operation, due to not realizing that kernel_ulong_t is a type. julia > Done using Coccinelle. > Based on a suggestion by Joe Perches <joe@perches.com>. > > Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> > > --- > The semantic patch seems too long for a commit log, but is in the cover > letter. > > drivers/spi/spi-dw-pci.c | 4 ++-- > 1 file changed, 2 insertions(+), 2 deletions(-) > > diff --git a/drivers/spi/spi-dw-pci.c b/drivers/spi/spi-dw-pci.c > index ef7db75..60198a3 100644 > --- a/drivers/spi/spi-dw-pci.c > +++ b/drivers/spi/spi-dw-pci.c > @@ -29,13 +29,13 @@ struct spi_pci_desc { > u16 bus_num; > }; > > -static struct spi_pci_desc spi_pci_mid_desc_1 = { > +static const struct spi_pci_desc spi_pci_mid_desc_1 = { > .setup = dw_spi_mid_init, > .num_cs = 5, > .bus_num = 0, > }; > > -static struct spi_pci_desc spi_pci_mid_desc_2 = { > +static const struct spi_pci_desc spi_pci_mid_desc_2 = { > .setup = dw_spi_mid_init, > .num_cs = 2, > .bus_num = 1, > > -- > To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > -- To unsubscribe from this list: send the line "unsubscribe linux-spi" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

For structure types defined in the same file or local header files, find top-level static structure declarations that have the following properties: 1. Never reassigned. 2. Address never taken 3. Not passed to a top-level macro call 4. No pointer or array-typed field passed to a function or stored in a variable. Declare structures having all of these properties as const. Done using Coccinelle. Based on a suggestion by Joe Perches <joe@perches.com>.
