Subject: [PATCH 06/14] net: dpaa2-mac: remove defensive check in
|
|
dpaa2_mac_disconnect()
|
|
|
|
dpaa2_mac_disconnect() will only be called with a NULL mac->phylink if
|
|
dpaa2_mac_connect() failed, or was never called.
|
|
|
|
The callers are these:
|
|
|
|
dpaa2_eth_disconnect_mac():
|
|
|
|
if (dpaa2_eth_is_type_phy(priv))
|
|
dpaa2_mac_disconnect(priv->mac);
|
|
|
|
dpaa2_switch_port_disconnect_mac():
|
|
|
|
if (dpaa2_switch_port_is_type_phy(port_priv))
|
|
dpaa2_mac_disconnect(port_priv->mac);
|
|
|
|
priv->mac can be NULL, but in that case, dpaa2_eth_is_type_phy() returns
|
|
false, and dpaa2_mac_disconnect() is never called. Similar for
|
|
dpaa2-switch.
|
|
|
|
When priv->mac is non-NULL, it means that dpaa2_mac_connect() returned
|
|
zero (success), and therefore, priv->mac->phylink is also a valid
|
|
pointer.
