Subject: [PATCH v10 07/17] virtio: Don't set FAILED status bit on device index allocation failure
Date: Thu, 29 Jul 2021 15:34:53 +0800 [thread overview]
Message-ID: <20210729073503.187-8-xieyongji@bytedance.com> (raw)
In-Reply-To: <20210729073503.187-1-xieyongji@bytedance.com>
We don't need to set FAILED status bit on device index allocation
failure since the device initialization hasn't been started yet.
This doesn't affect runtime, found in code review.
