This can produce false positives for things like: $ ./scripts/checkpatch.pl -f drivers/staging/comedi/comedidev.h WARNING: Missing a blank line after declarations #60: FILE: drivers/staging/comedi/comedidev.h:60: + const struct comedi_lrange *range_table; + const struct comedi_lrange *const *range_table_list; Fix the $Type variable to support matching multiple "* const" uses.
