hwmon: (axi-fan-control) Fix possible NULL pointer dereference
CVE-2023-52863
Description
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (axi-fan-control) Fix possible NULL pointer dereference
axi_fan_control_irq_handler(), dependent on the private axi_fan_control_data structure, might be called before the hwmon device is registered. That will cause an "Unable to handle kernel NULL pointer dereference" error.
