Without this change I can't set an attribute exactly PAGE_SIZE in
length. There is no need for zero termination because the interface
uses lengths.

I think we need this patch or we might "lose" devices to the dpm_irq_off
list if a failure occurs during the suspend process.

o Following patch sets the attributes for newly allocated inodes for sysfs
objects. If the object has non-default attributes, inode attributes are
set as saved in sysfs_dirent->s_iattr, pointer to struct iattr.

o This adds ->i_op->setattr VFS method for sysfs inodes. The changed
attribues are saved in the persistent sysfs_dirent structure as a pointer
to struct iattr. The struct iattr is allocated only for those sysfs_dirent's
for which default attributes are getting changed. Thanks to Jon Smirl for
this suggestion.

o The following patch makes sure to attach sysfs_dirent to the dentry before
allocation a new inode through sysfs_create(). This change is done as
preparatory work for implementing ->i_op->setattr() functionality for
sysfs objects.

Finally (phew!) this patch demonstrates how to adapt the adm1026 to
take advantage of the new callbacks, and the i2c-sysfs.h defined
structure/macros. Most of the other sensor/hwmon drivers could be
updated in the same way. The odd few exceptions (bmcsensors for
example) however might be better off with their own custom attribute
structure.

This patch creates a new header with a potential standard i2c sensor
attribute type (which simply includes an int representing the sensor
number/index) and the associated macros, SENSOR_DEVICE_ATTR to define
a static attribute and to_sensor_dev_attr to get a
sensor_device_attribute reference from an embedded device_attribute
reference.

This patch adds the device_attribute paramerter to the
device_attribute store and show sysfs callback functions, and passes a
reference to the attribute when the callbacks are called.
