Staging: aten2011: remove unused fields from structures.
As the driver was copied from another one, there are lots of fields that are unused due to the hardware being different. Remove a bunch of them, more will be removed later. Cc: Russell Lang <gsview@ghostgum.com.au> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
