Descriptions

In the Linux kernel, the following vulnerability has been resolved: arm64: dts: imx8mm-verdin: Do not power down eth-phy Currently if suspending using either freeze or memory state, the fec
driver tries to power down the phy which leads to crash of the kernel
and non-responsible kernel with the following call trace: [ 24.839889 ] Call trace:

[ 24.839932 ] ret_from_fork+0x10/0x20 Since there is currently no functionality in the phy subsystem to power
down phys let's just disable the feature of powering-down the ethernet
phy.
