Subject: [PATCH v4 0/2] sysfs: finalize the constification of 'struct
 bin_attribute'

All users have been migrated to the new const types and variables.
Get rid of the transition machinery.

After applying, make sure no leftovers are left:
$ git grep bin_attrs_new
$ git grep read_new ':!drivers/block/swim_asm.S'
$ git grep write_new ':!drivers/cpufreq/powernow-k8.c' ':!drivers/s390/char/monwriter.c'
