[PATCH v2 03/11] KVM: arm64: selftests: Remove print_reg's dependency on vcpu_config
From: Haibo Xu
Date: Thu May 25 2023 - 03:35:41 EST
From: Andrew Jones <ajones@xxxxxxxxxxxxxxxx>
print_reg() and its helpers only use the vcpu_config pointer for
config_name(). So just pass the config name in instead, which is used
as a prefix in asserts. print_reg() can now be compiled independently
of config_name().
