[PATCH 02/11] KVM: PPC: Book3S HV: Improve a size determination in kvmppc_alloc_hpt()

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Fri, 20 Jan 2017 10:00:13 +0100

Replace the specification of a data structure 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.
