Subject: PCI: designware-ep: Remove static keyword from dw_pcie_ep_reset_bar()
Git-commit: 9e7181199e1b623c94bda02a63728f62b00ea915
Patch-mainline: v4.16-rc1
References: fate#326536, fate#326532
Remove the static keyword from dw_pcie_ep_reset_bar() so that
pci-dra7xx.c does not need its own copy of dw_pcie_ep_reset_bar().
