[Qemu-devel] [PATCH 02/28] i386: kvm: kvm_arch_get_supported_cpuid: clean up has_kvm_features check

[Marcelo Tosatti]

From: Eduardo Habkost <address@hidden>

Instead of a function-specific has_kvm_features variable, simply use a
"found" variable that will be checked in case we have to use the legacy
get_para_features() interface.

No behavior change, just code cleanup.
