checkpatch: allow parentheses on return handle array values
Andy Whitcroft [Thu, 15 Jan 2009 21:51:06 +0000 (13:51 -0800)]
When we allow return to have surrounding parentheses when containing
comparison operators we are not correctly handling the case where the
values contain array sufffixes.  Squash them.
