From a307593a644443db12888f45eed0dafb5869e2cc Mon Sep 17 00:00:00 2001 From: Doug Berger Date: Mon, 18 May 2020 15:23:59 -0700 Subject: [PATCH] net: phy: simplify phy_link_change arguments This function was introduced to allow for different handling of link up and link down events particularly with regard to the netif_carrier. The third argument do_carrier allowed the flag to be left unchanged. Since then the phylink has introduced an implementation that completely ignores the third parameter since it never wants to change the flag and the phylib always sets the third parameter to true so the flag is always changed. Therefore the third argument (i.e. do_carrier) is no longer necessary and can be removed. This also means that the phylib phy_link_down() function no longer needs its second argument.
