Subject: [PATCH] PCI: Export pcie_has_flr()
Git-commit: 2d2917f7747805a1f4188672f308d82a8ba01700
Patch-mainline: v4.19-rc1
References: bsc#1120058

pcie_flr() suggests pcie_has_flr() to ensure that PCIe FLR support is
present prior to calling.  pcie_flr() is exported while pcie_has_flr()
is not.  Resolve this.
