Subject: [PATCH AUTOSEL 4.19 115/671] net: phy: micrel: set soft_reset callback to genphy_soft_reset for KSZ9031

From: Heiner Kallweit <hkallweit1@...il.com>

[ Upstream commit 1d16073a326891c2a964e4cb95bc18fbcafb5f74 ]

So far genphy_soft_reset was used automatically if the PHY driver
didn't implement the soft_reset callback. This changed with the
mentioned commit and broke KSZ9031. To fix this configure the
KSZ9031 PHY driver to use genphy_soft_reset.

Fixes: 6e2d85ec0559 ("net: phy: Stop with excessive soft reset")
