arcnet: com90xx: Mark expected switch fall-throughs

2019-07-29T16:38:34Z

Mark switch cases where we are expecting to fall through. This patch fixes the following warnings (Building: powerpc allyesconfig): drivers/net/arcnet/com90xx.c: In function 'com90xx_setup': include/linux/printk.h:304:2: warning: this statement may fall through [-Wimplicit-fallthrough=] printk(KERN_ERR pr_fmt(fmt), ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/net/arcnet/com90xx.c:695:3: note: in expansion of macro 'pr_err' pr_err("Too many arguments\n"); ^~~~~~ drivers/net/arcnet/com90xx.c:696:2: note: here case 3: /* Mem address */ ^~~~ drivers/net/arcnet/com90xx.c:697:9: warning: this statement may fall through [-Wimplicit-fallthrough=] shmem = ints[3]; ~~~~~~^~~~~~~~~ drivers/net/arcnet/com90xx.c:698:2: note: here case 2: /* IRQ */ ^~~~ drivers/net/arcnet/com90xx.c:699:7: warning: this statement may fall through [-Wimplicit-fallthrough=] irq = ints[2]; ~~~~^~~~~~~~~ drivers/net/arcnet/com90xx.c:700:2: note: here case 1: /* IO address */ ^~~~ Reported-by: Stephen Rothwell Signed-off-by: Gustavo A.

Annotate hardware config module parameters in drivers/net/arcnet/

2017-04-20T11:02:32Z

When the kernel is running in secure boot mode, we lock down the kernel to prevent userspace from modifying the running kernel image. Whilst this includes prohibiting access to things like /dev/mem, it must also prevent access by means of configuring driver modules in such a way as to cause a device to access or modify the kernel image. To this end, annotate module_param* statements that refer to hardware configuration and indicate for future reference what type of parameter they specify. The parameter parser in the core sees this information and can skip such parameters with an error message if the kernel is locked down. The module initialisation then runs as normal, but just sees whatever the default values for those parameters is. Note that we do still need to do the module initialisation because some drivers have viable defaults set in case parameters aren't specified and some drivers support automatic configuration (e.g. PNP or PCI) in addition to manually coded parameters. This patch annotates drivers in drivers/net/arcnet/. Suggested-by: Alan Cox Signed-off-by: David Howells cc: Michael Grzeschik cc: netdev@vger.kernel.org

arcnet: com90xx: add __init attribute

2016-04-20T00:17:45Z

Add __init attribute on a function that is only called from other __init functions and that is not inlined, at least with gcc version 4.8.4 on an x86 machine with allyesconfig. Currently, the function is put in the .text.unlikely segment. Declaring it as __init will cause it to be put in the .init.text and to disappear after initialization. The result of objdump -x on the function before the change is as follows: 0000000000000000 l F .text.unlikely 00000000000000bf check_mirror And after the change it is as follows: 0000000000000000 l F .init.text 00000000000000ba check_mirror Done with the help of Coccinelle. The semantic patch checks for local static non-init functions that are called from an __init function and are not called from any other function.

Simplify and make consistent the current uses of inb/outb by using the newly introduced arcnet_ equivalents. o Add new #defines for register offsets o Remove old #defines that included the ioaddr o Remove obfuscating macros by expanding them in-place where appropriate Signed-off-by: Joe Perches Signed-off-by: Michael Grzeschik

arcnet: Move files out of include/linux

2015-09-23T06:44:25Z
These #include files don't need to be in the include/linux directory as they can be local to drivers/net/arcnet/ Move them and update the #include statements. Update the MAINTAINERS file pattern by deleting arcdevice from the NETWORKING block as arcnet is currently unmaintained. Signed-off-by: Joe Perches Signed-off-by: Michael Grzeschik

2015-09-23T06:44:24Z
These macros don't actually represent BUG uses but are more commonly used as logging macros, so use a more kernel style macro. Convert the BUGMSG from a netdev_ like use to actually use netdev_. Signed-off-by: Joe Perches Signed-off-by: Michael Grzeschik
