Subject: [PATCH net v1] net: phy: smsc: fix printing too many logs
Date: Wed, 17 Jun 2020 23:33:40 +0800	[thread overview]
Message-ID: <20200617153340.17371-1-zhengdejin5@gmail.com> (raw)

Commit 7ae7ad2f11ef47 ("net: phy: smsc: use phy_read_poll_timeout()
to simplify the code") will print a lot of logs as follows when Ethernet
cable is not connected:

[    4.473105] SMSC LAN8710/LAN8720 2188000.ethernet-1:00: lan87xx_read_status failed: -110

So fix it by read_poll_timeout().

Fixes: 7ae7ad2f11ef47 ("net: phy: smsc: use phy_read_poll_timeout() to simplify the code")
