net: phy: xgmiitorgmii: Support generic PHY status read
[ Upstream commit 197f9ab7f08ce4b9ece662f747c3991b2f0fbb57 ]
Some PHY drivers like the generic one do not provide a read_status
callback on their own but rely on genphy_read_status being called
directly.
With the current code, this results in a NULL function pointer call.
Call genphy_read_status instead when there is no specific callback.
Fixes: f411a6160bd4 ("net: phy: Add gmiitorgmii converter support")
