The newly added pcie-rockchip driver fails to initialize the io_size variable if the DT doesn't provide ranges for the PCI I/O space, as found by building it with -Wmaybe-uninitialized: drivers/pci/host/pcie-rockchip.c: In function 'rockchip_pcie_probe': drivers/pci/host/pcie-rockchip.c:1007:6: warning: 'io_size' may be used uninitialized in this function [-Wmaybe-uninitialized] This adds an appropriate initialization immediately in front of the loop, so the io_size is zero as expected afterwards for that case.
