NAME

       pci_set_cacheline_size - ensure the CACHE_LINE_SIZE register is programmed

SYNOPSIS

       int pci_set_cacheline_size(struct pci_dev * dev);

ARGUMENTS

	   the PCI device for which MWI is to be enabled

DESCRIPTION

       Helper function for pci_set_mwi. Originally copied from drivers/net/acenic.c. Copyright 1998-2001 by Jes Sorensen, <jestrained-monkey.org>.

RETURNS

NAME

       device_create_with_groups - creates a device and registers it with sysfs

SYNOPSIS

       struct device * device_create_with_groups(struct class * class, struct device * parent, dev_t devt, void * drvdata,
						 const struct attribute_group ** groups, const char * fmt, ...);

ARGUMENTS

       class
	   pointer to the struct class that this device should be registered to

       parent
	   pointer to the parent struct device of this new device, if any

       devt
	   the dev_t for the char device to be added

       drvdata
	   the data to be added to the device for callbacks

       groups
	   NULL-terminated list of attribute groups to be created

       fmt
	   string for the device's name

       ...
	   variable arguments

DESCRIPTION

       This function can be used by char device classes. A struct device will be created in sysfs, registered to the specified class. Additional
       attributes specified in the groups parameter will also be created automatically.

       A "dev" file will be created, showing the dev_t for the device, if the dev_t is not 0,0. If a pointer to a parent struct device is passed
       in, the newly created struct device will be a child of that device in sysfs. The pointer to the struct device will be returned from the
       call. Any further sysfs files that might be required can be created using this pointer.

       Returns struct device pointer on success, or ERR_PTR on error.

NOTE

       the struct class passed to this function must have previously been created with a call to class_create.
