Subject: [PATCH 4.2.y-ckt 97/98] net: moxa: fix an error code

4.2.8-ckt6 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

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

commit 1d3cd1773fddfdc9ffb0c2dec9a954c7a54bc207 upstream.

We accidentally return IS_ERR(priv->base) which is 1 instead of
PTR_ERR(priv->base) which is the error code.

Fixes: 6c821bd9edc9 ('net: Add MOXA ART SoCs ethernet driver')
