Subject: [PATCH 13/17] s390/debug: Improve a size determination in
 debug_open()

* Replace the specification of a data type by a pointer dereference
  as the parameter for the operator "sizeof" to make the corresponding size
  determination a bit safer according to the Linux coding style convention.

* Improve source code layout for one function call.
