But again, of_device_get_match_data() returns void *, and we need
"uintptr_t" in order to type cast it properly (at-least without
warning).

Also, while looking around found the similar warning for other file
where it uses " of_device_get_match_data()"
drivers/pci/controller/pcie-iproc-platform.c:56:15: warning: cast to
smaller integer type 'enum iproc_pcie_type' from 'const void *'
[-Wvoid-pointer-to-enum-cast]
pcie->type = (enum iproc_pcie_type) of_device_get_match_data(dev);

Thanks
