Subject: [PATCH] net: intel: e1000e: add check on e1e_wphy() return value

From: "Gustavo A. R. Silva" <[email-masked]>
Date: Tue, 20 Jun 2017 16:22:34 -0500

Check return value from call to e1e_wphy(). This value is being
checked during previous calls to function e1e_wphy() and it seems
a check was missing here.
