From 394e1b93f439da5238231bbd5e31f35ec1bd7948 Mon Sep 17 00:00:00 2001 From: Frederick Lawler Date: Wed, 17 Jul 2019 21:07:43 -0500 Subject: [PATCH] scsi: csiostor: Prefer pcie_capability_read_word() Commit 474ed167ebbe ("PCI: Add accessors for PCI Express Capability") added accessors for the PCI Express Capability so that drivers didn't need to be aware of differences between v1 and v2 of the PCI Express Capability. Replace pci_read_config_word() and pci_write_config_word() calls with pcie_capability_read_word() and pcie_capability_write_word(). Signed-off-by: Frederick Lawler Signed-off-by: Martin K.
