Subject: [PATCH 4.4 163/163] extcon: max77843: Use correct size for reading the interrupt register

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@...cle.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.
