[PATCH 02/19] KVM: selftests: Zero out the correct page in the Hyper-V features test

From: Sean Christopherson
Date: Tue Jun 22 2021 - 16:05:56 EST


Fix an apparent copy-paste goof in hyperv_features where hcall_page
(which is two pages, so technically just the first page) gets zeroed
twice, and hcall_params gets zeroed none times.
