     the boot CPU after suspend-to-RAM (Rafael Wysocki).

     can trigger a divide by zero if the driver is accessed via sysfs
     before it manages to take the first sample and one causing it to
     fail to update a structure field used in a trace point, so the

     by registering cpufreq-dt (which subsequently doesn't work)
     unconditionally and preventing the driver that would actually work
     from registering (Sudeep Holla).

   - Stable-candidate fix for an ARM64 cpuidle issue causing idle state
     usage counters to be incorrectly updated for idle states that were
     not entered due to errors (James Morse).

   - Fix for a recently introduced issue in the OPP (Operating
     Performance Points) framework causing it to print bogus error
     messages for missing optional regulators (Viresh Kumar).

   - Fix for a recently introduced issue in the generic device
     properties framework that may cause it to attempt to dereferece and
     invalid pointer in some cases (Heikki Krogerus).
