3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpen...@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.)
Fixes: 974cc7b93441 ("mfd: vexpress: Define the device as MFD cells")
