Subject: [PATCH 01/11] virtio: pci: Fix discovery of device config length
Date: Sun, 20 Mar 2022 11:41:08 +0000	[thread overview]
Message-ID: <20220320114118.2237795-2-ascull@google.com> (raw)
In-Reply-To: <20220320114118.2237795-1-ascull@google.com>

The length of the device config was erroneously being taken from the
notify capability. Correct this by finding the length in the device
capability.
