[PATCH 3.2 111/152] sysfs.h: add ATTRIBUTE_GROUPS() macro

[Ben Hutchings]

3.2.67-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>

commit f2f37f58b1b933b06d6d84e80a31a1b500fb0db2 upstream.

To make it easier for driver subsystems to work with attribute groups,
create the ATTRIBUTE_GROUPS macro to remove some of the repetitive
typing for the most common use for attribute groups.
