[PATCH] KVM: PPC: Book3S HV: fix the return value of kvm_age_rmapp()
From: Bo Liu
Date: Fri Apr 01 2022 - 02:55:14 EST
The return value type defined in the function kvm_age_rmapp() is
"bool", but the return value type defined in the implementation of the
function kvm_age_rmapp() is "int".
Change the return value type to "bool".
