Subject: [PATCH 04/13] net: phy: at803x: move qca83xx specific check in
|
|
dedicated functions
|
|
|
|
Rework qca83xx specific check to dedicated function to tidy things up
|
|
and drop useless phy_id check.
|
|
|
|
Also drop an useless link_change_notify for QCA8337 as it did nothing an
|
|
returned early.
