[PATCH] PCI: mediatek: fix error handling in mtk_pcie_parse_and_add_res()

Show all headers | View raw

The 'linkup' variable would always increment by one whether the link
status is true or not. Therefore, this patch fixes the return value in
mtk_pcie_parse_and_add_res() and removes unnecessary 'linkup' variable.
