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