  3. Subject: [PATCH] net: phy: broadcom: use auxctl reading helper in BCM54612E
  4. code

  8. Starting with commit 5b4e29005123 ("net: phy: broadcom: add
  9. bcm54xx_auxctl_read") we have a reading helper so use it and avoid code
  10. duplication.
  11. It also means we don't need MII_BCM54XX_AUXCTL_SHDWSEL_MISC define as
  12. it's the same as MII_BCM54XX_AUXCTL_SHDWSEL_MISC just for reading needs
  13. (same value shifted by 12 bits).
