net: dsa: Fix type was not set for devlink port
If PHY is not available on DSA port (described at devicetree but absent or failed to detect) then kernel prints warning after 3700 secs: [ 3707.948771] ------------[ cut here ]------------ [ 3707.948784] Type was not set for devlink port. [ 3707.948894] WARNING: CPU: 1 PID: 17 at net/core/devlink.c:8097 0xc083f9d8 We should unregister the devlink port as a user port and re-register it as an unused port before executing "continue" in case of dsa_port_setup error. Fixes: 86f8b1c01a0a ("net: dsa: Do not make user port errors fatal") Signed-off-by: Maxim Kochetkov <fido_max@inbox.ru> Reviewed-by: Vladimir Oltean <olteanv@gmail.com> Signed-off-by: David S.
