4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@oracle.com>
commit c4924e92442d7218bd725e47fa3988c73aae84c9 upstream.
The info->status[] array has 3 elements. We are using size MAX77843_MUIC_IRQ_NUM (16) instead of MAX77843_MUIC_STATUS_NUM (3) as intended.
