Subject: linux-next: build warning after merge of the devicetree tree

Hi all,

After merging the devicetree tree, today's linux-next build (powerpc
allnoconfig) produced this warning:

drivers/of/address.c: In function 'of_pci_range_to_resource':
drivers/of/address.c:244:45: warning: passing argument 1 of 'pci_register_io_range' discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
  244 |                 err = pci_register_io_range(&np->fwnode, range->cpu_addr,
      |                                             ^~~~~~~~~~~
In file included from drivers/of/address.c:12:

      |                                         ~~~~~~~~~~~~~~~~~~~~~~^~~~~~
