Hi Everyone,

This series of patches consists of a fix for a possible (and actually happening
in some cases) NULL pointer dereference in cpufreq_update_limits() (patch
[01/10]) and a bunch of tangentially related fixes inspired by it, mostly about
using __free() for cleanup and locking guards.

The first patch is definitely for 6.15, but the rest is rather 6.16 material.

Please refer to the individual patch changelogs for more information.

Thanks!
