Subject: [PATCH v6 08/21] selftests: KVM: Fix kvm device helper ioctl assertions
Date: Wed,  4 Aug 2021 08:58:06 +0000	[thread overview]
Message-ID: <20210804085819.846610-9-oupton@google.com> (raw)
In-Reply-To: <20210804085819.846610-1-oupton@google.com>

The KVM_CREATE_DEVICE and KVM_{GET,SET}_DEVICE_ATTR ioctls are defined
to return a value of zero on success. As such, tighten the assertions in
the helper functions to only pass if the return code is zero.
