Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
net: mdio: Check regmap pointer returned by device_node_to_regmap()<br />
<br />
The call to device_node_to_regmap() in airoha_mdio_probe() can return<br />
an ERR_PTR() if regmap initialization fails. Currently, the driver<br />
stores the pointer without validation, which could lead to a crash<br />
if it is later dereferenced.<br />
<br />
Add an IS_ERR() check and return the corresponding error code to make<br />
the probe path more robust.
