KVM: PPC: e500: Replace kzalloc() calls by kcalloc() in two functions
* A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "kcalloc".
Suggested-by: Paolo Bonzini <pbonzini@redhat.com>
This issue was detected also by using the Coccinelle software.
* Replace the specification of data structures by pointer dereferences
to make the corresponding size determination a bit safer according to
the Linux coding style convention.
