PCI: Allow VPD access for QLogic ISP2722
commite00dc69b5f
upstream.0d5370d1d8
("PCI: Prevent VPD access for QLogic ISP2722") disabled access to VPD of the ISP2722-based 16/32Gb Fibre Channel to PCIe Adapter because reading past the end of the VPD caused NMIs.104daa71b3
("PCI: Determine actual VPD size on first access") limits reads to the actual size of VPD, which should prevent these NMIs.104daa71b3
was merged *before*0d5370d1d8
, but we think the testing that prompted0d5370d1d8
("PCI: Prevent VPD access for QLogic ISP2722") was done with a kernel that lacked104daa71b3
. See [1, 2]. Remove the quirk added by0d5370d1d8
("PCI: Prevent VPD access for QLogic ISP2722") so customers can read the HBA VPD.
