CVE-2021-47372

Description

In the Linux kernel, the following vulnerability has been resolved:

net: macb: fix use after free on rmmod

plat_dev->dev->platform_data is released by platform_device_unregister(), use of pclk and hclk is a use-after-free. Since device unregister won't need a clk device we adjust the function call sequence to fix this issue.
