Message-Id: <201401040421.56307.sergei.shtylyov@cogentembedded.com>
Date: Sat, 4 Jan 2014 04:21:56 +0300
From: Sergei Shtylyov <sergei.shtylyov@...entembedded.com>
To: netdev@...r.kernel.org
Subject: [PATCH 5/6] phylib: remove unused adjust_state callback
Remove adjust_state() callback from 'struct phy_device' since it seems to have
never been really used from the inception: phy_start_machine() has been always
called with 2nd argument equal to NULL.
