This series simplify mps and mrrs setting related code in drivers.
Export the pcie_set/get_mps() like pcie_set/get_readrq(). So drivers
can use these interfaces to simplify code that set mps and mrrs.
Patch 2 use pci_is_root_bus() instead of if (bus->parent) statement
for better readability.
Yijing Wang (6):
PCI: Export pcie_set_mps() and pcie_get_mps()
title/pci: use cached pci_dev->pcie_mpss to simplify code
IB/qib: Use pci_is_root_bus() to check whether it is a root bus
IB/qib: Use pcie_set_mps() and pcie_get_mps() to simplify code
staging/et131x: Use cached pci_dev->pcie_mpss and pcie_set_readrq()
to simplif code
radeon: Use pcie_get_readrq() and pcie_set_readrq() to simplify code
