Subject: Driver core: fix deprectated sysfs structure for nested class devices
From: Dmitry Torokhov <[EMAIL PROTECTED]>

Nested class devices used to have 'device' symlink point to a real
(physical) device instead of a parent class device.  When converting
subsystems to struct device we need to keep doing what class devices did if
CONFIG_SYSFS_DEPRECATED is Y, otherwise parts of udev break.
