From: Dan Carpenter dan.carpenter@oracle.com
commit f8a70d8b889f180e6860cb1f85fed43d37844c5a upstream.
The > comparison should be >= to prevent reading beyond the end of the func->template[] array.
(The func->template array is allocated in vexpress_syscfg_regmap_init() and it has func->num_templates elements.)
