Subject: [PATCH] net: phy: use generic clause 45 autonegotiation done
Date:   Wed, 18 Jul 2018 16:12:15 +0300
Message-Id: <1531919535-20269-1-git-send-email-camelia.groza@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Only Clause 22 PHYs can use genphy_aneg_done(). Use
genphy_c45_aneg_done() for PHYs that implement Clause 45 without
the Clause 22 register set.

This change follows the model of phy_restart_aneg() which
differentiates between the two implementations in a similar way.

Fixes: 41408ad519f7 ("net: phy: avoid genphy_aneg_done() for PHYs without clause 22 support")
