Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
pmdomain: arm: Fix NULL dereference on scmi_perf_domain removal
On unloading of the scmi_perf_domain module got the below splat, when in the DT provided to the system under test the '#power-domain-cells' property was missing. Indeed, this particular setup causes the probe to bail out early without giving any error, which leads to the ->remove() callback gets to run too, but without all the expected initialized structures in place.
Add a check and bail out early on remove too.
