[PATCH] s390: use normal switch statement for ioctls in dasd_ioctlc
Add an ->ioctl method to the dasd_discipline structure. This allows to apply
the same kind of cleanups the last patch applied to dasd_ioctl.c to
dasd_eckd.c (the only dasd discipline with special ioctls) aswell.
Again lots of code removed. During auditing the ioctls I found two fishy
return value propagations from copy_{from,to}_user, maintainers please check
those, I've marked them with XXX comments.
