Merge tag 'devicetree-fixes-for-4.14-2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull DeviceTree fixes from Rob Herring:
- Fix memory leak in error case of of_console_check
- Increase number of reserved memory regions to 32. 16 was not enough
on some Power systems.
- Fix OF node refcounting for of_fwnode_graph_get_port_parent
* tag 'devicetree-fixes-for-4.14-2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux:
device property: preserve usecount for node passed to of_fwnode_graph_get_port_parent()
drivers: of: increase MAX_RESERVED_REGIONS to 32
of: do not leak console options
