[PATCH v3 2/8] KVM: selftests: x86: sync_regs_test: Get regs structure before modifying it
From: Thomas Huth
Date: Thu Feb 08 2024 - 15:49:40 EST
The regs structure just accidentally contains the right values
from the previous test in the spot where we want to change rbx.
It's cleaner if we properly initialize the structure here before
using it.
