[PATCH] checkpatch: Allow multiple const * types

From: Joe Perches
Date: Fri Jun 27 2014 - 13:49:18 EST


checkpatch's $Type variable does not match declarations
of multiple const * types.

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.
