[PATCH net v3 0/2] net: Fix return value check for fixed_phy_register()

[Ruan Jinjie]

The fixed_phy_register() function returns error pointers and never
returns NULL. Update the checks accordingly.

Changes in v3:
- Drop the error fix patch for fixed_phy_get_gpiod().
- Split the error code update code into another patch set as suggested.
- Update the commit title and message.

Ruan Jinjie (2):
  net: bgmac: Fix return value check for fixed_phy_register()
  net: bcmgenet: Fix return value check for fixed_phy_register()
