Subject[PATCH 3.16 009/305] s390/dasd: Restore a necessary cast
3.16.63-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Ben Hutchings <ben@decadent.org.uk>

Commit c3925a3da617 "s390/dasd: fix IO error for newly defined
devices" removed a cast of dasd_device::private which was not
necessary in the upstream code. However, in 3.16 the type of
dasd_device::private is char *, so the cast is still needed.
