mtd: do not use plain 0 as NULL
The first 3 arguments of 'mtd_device_parse_register()' are pointers, but many callers pass '0' instead of 'NULL'. Fix this globally. Thanks to coccinelle for making it easy to do with the following semantic patch: @@ expression mtd, types, parser_data, parts, nr_parts; @@ ( -mtd_device_parse_register(mtd, 0, parser_data, parts, nr_parts) +mtd_device_parse_register(mtd, NULL, parser_data, parts, nr_parts) | -mtd_device_parse_register(mtd, types, 0, parts, nr_parts) +mtd_device_parse_register(mtd, types, NULL, parts, nr_parts) | -mtd_device_parse_register(mtd, types, parser_data, 0, nr_parts) +mtd_device_parse_register(mtd, types, parser_data, NULL, nr_parts) ) Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
