  To: Martin K. Petersen
  Cc: linux-scsi, target-devel, linux-kernel, Thomas Weißschuh

In preparation for the constification of configfs attributes, make the
pointers to struct configfs_attribute in the target subsystem and its
drivers const and use the new ct_attrs_const field of struct
config_item_type.

Signed-off-by: Thomas Weißschuh <linux@weissschuh.net>

This is only sent to the target subsystem maintainers and not the driver
maintainers to avoid spamming the maintainers.
