Subject: PCI: dra7xx: Use dw_pcie_link_up() consistently
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=30fb7ba6605671e575b6a7a2e69fe153d6d20141;p=linux-beck.git

PCI: dra7xx: Use dw_pcie_link_up() consistently

We already use dw_pcie_link_up() once in dra7xx_pcie_establish_link(), but
we duplicate its code later.  Use dw_pcie_link_up() for consistency.  No
functional change.
