Subject: [PATCH net-next 1/4] PCI/VPD: Remove Chelsio T3 quirk
Date: Tue, 2 Feb 2021 21:35:55 +0100	[thread overview]
Message-ID: <a64e550c-b8d2-889e-1f55-019b10060c1b@gmail.com> (raw)
In-Reply-To: <b07dc99d-7fd0-48c0-3fc4-89cda90ee5d7@gmail.com>

cxgb3 driver doesn't use the PCI core code for VPD access, it has its own
implementation. Therefore we don't need a quirk for it in the core code.
