dsa: mv88e6xxx: Fix unsigned/signed issue
commit dea870242a9c ("dsa: mv88e6xxx: Allow speed/duplex of port to be
configured") leads to the following static checker warning:
drivers/net/dsa/mv88e6xxx.c:585 mv88e6xxx_adjust_link()
warn: unsigned 'ret' is never less than zero.
drivers/net/dsa/mv88e6xxx.c
573 void mv88e6xxx_adjust_link(struct dsa_switch *ds, int port,
574 struct phy_device *phydev)
575 {
576 struct mv88e6xxx_priv_state *ps = ds_to_priv(ds);
577 u32 ret, reg;
578
579 if (!phy_is_pseudo_fixed_link(phydev))
580 return;
581
582 mutex_lock(&ps->smi_mutex);
583
584 ret = _mv88e6xxx_reg_read(ds, REG_PORT(port), PORT_PCS_CTRL);
585 if (ret < 0)
Make ret an int, which is the return type for _mv88e6xxx_reg_read()
