I/O resource flags consist of I/O resource types and modifier bits. Therefore, checking an I/O resource type in 'flags' must be performed with a bitwise operation. Fix find_next_iomem_res() and region_intersects() that simply compare 'flags' against a given value. Also change __request_region() to set 'res->flags' from resource_type() and resource_ext_type() of the parent, so that children nodes will inherit the extended I/O resource type.
