[PATCH] kernel-doc: allow space after __attribute__

[Randy Dunlap <randy.dunlap@oracle.com>]

From: Randy Dunlap <randy.dunlap@oracle.com>

Allow space(s) between "__attribute__" and "((blah))" so that
kernel-doc does not complain like:

Warning(/tester/linsrc/linux-2.6.20-git15//kernel/timer.c:939): No description found for parameter 'read_persistent_clock(void'
