Christoph Hellwig 22a685d09b [PATCH] officially deprecate register_ioctl32_conversion
These have been deprecated since ->compat_ioctl when in, thus only a short
deprecation period.  There's four users left: i2o_config, s390/z90crypy,
s390/dasd and s390/zfcp and for the first two patches are about to be
submitted to get rid of it.
