Subject: Regression in 4.19 net/phy/realtek: garbled sysfs output

Hi,

Since 4.19 r8169 depends on phylib:

$lsmod | grep r8169
r8169                  81920  0
libphy                 57344  2 r8169,realtek

Unfortunately this now gives me the following sysfs error:

$cd /sys/module/realtek/drivers
$ls -l
ls: cannot access 'mdio_bus:RTL8201F 10/100Mbps Ethernet': No such file or directory
total 0
lrwxrwxrwx 1 root root 0 Oct 24 21:09 'mdio_bus:RTL8201CP Ethernet' -> '../../../bus/mdio_bus/drivers/RTL8201CP Ethernet'
l????????? ? ?    ?    ?            ? 'mdio_bus:RTL8201F 10/100Mbps Ethernet'
lrwxrwxrwx 1 root root 0 Oct 24 21:09 'mdio_bus:RTL8211 Gigabit Ethernet' -> '../../../bus/mdio_bus/drivers/RTL8211 Gigabit Ethernet'
[..]

Apparently the forward slash in "10/100Mbps Ethernet" is interpreted as
directory separator that leads nowhere, and was introduced in commit
513588dd44b ("net: phy: realtek: add RTL8201F phy-id and functions").

Would it be acceptable to change the name simply to "RTL8201F Ethernet"?

thanks,
Holger
