This patch causes an error to be returned if the user attempts to write a
sysfs file at a nonzero offset. Because sysfs store methods do not
support a position parameter, the behavior in this case would be
unpredictable. Thus, we return an error, because at least now we're
consistent.
This patch generated from 2.6.11-rc1.
Now with tabs.
