[PATCH v2 0/7] PCI: Prefer pcie_capability_read_word()

From: Bjorn Helgaas

From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>

Use pcie_capability_read_word() and similar instead of using
pci_read_config_word() directly. Add #defines to replace some magic
numbers. Fix typos in use of Transmit Margin field.

These are currently on my pci/misc branch for v5.5. Let me know if you see
any issues.

Bjorn Helgaas (5):
PCI: Add #defines for Enter Compliance, Transmit Margin
drm/amdgpu: Correct Transmit Margin masks
drm/amdgpu: Replace numbers with PCI_EXP_LNKCTL2 definitions
drm/radeon: Correct Transmit Margin masks
drm/radeon: Replace numbers with PCI_EXP_LNKCTL2 definitions

Frederick Lawler (2):
drm/amdgpu: Prefer pcie_capability_read_word()
drm/radeon: Prefer pcie_capability_read_word()
