Subject: [PATCH] pci: fix link maximum speed detection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit 8e09663 "pci: recognize/report GEN4 (PCIe 4.0) card 16GT/s Link
speed" introduced another speed into enum, but mistakenly also altered
field width, so one bit of link width was included there.

Resolves: https://bugzilla.redhat.com/1455017
