In the Linux kernel, the following vulnerability has been resolved:
net: phy: at803x: fix NULL pointer dereference on AR9331 PHY
Latest kernel will explode on the PHY interrupt config, since it depends
now on allocated priv. So, run probe to allocate priv to fix it.
ar9331_switch ethernet.1:10 lan0 (uninitialized): PHY [!ahb!ethernet@1a000000!mdio!switch@10:00] driver [Qualcomm Atheros AR9331 built-in PHY] (irq=13)
CPU 0 Unable to handle kernel paging request at virtual address 0000000a, epc == 8050e8a8, ra == 80504b34

Same Issue would affect some other PHYs (QCA8081, QCA9561), so fix it
too.
