   4 Subject: [PATCH 02/30] net: dsa: mt753x: remove mt753x_phylink_pcs_link_up()
   5
   6 Remove the mt753x_phylink_pcs_link_up() function for two reasons:
   7
   8 1) priv->pcs[i].pcs.neg_mode is set true, meaning it doesn't take a
   9    MLO_AN_FIXED anymore, but one of PHYLINK_PCS_NEG_*. However, this
  10    is inconsequential due to...
  11 2) priv->pcs[port].pcs.ops is always initialised to point at
  12    mt7530_pcs_ops, which does not have a pcs_link_up() member.
  13
  14 So, let's remove mt753x_phylink_pcs_link_up() entirely.
