[PATCH 0/3] net: fec: Reset ethernet PHY whenever the enet_out clock

This patchset fixes a regression introduced by commit 8fff755e9f8d ("net: fec: Ensure clocks are enabled while using mdio bus") for ethernet PHYs that are using ENET_OUT as reference clock (on i.MX6 or i.MX28) The first patch is a cleanup patch that removes redundant NULL checks. The second patch
