All the patches are independent of one another.

Patch 2 is straight cleanup no functional change but reduces the memory
footprint slightly.

Patch 3 is a bug that will only be seen when the PID is reset at init time
or when a change is made to PID params via debugfs.  The problem will only
exist for one sample time since it is setting last_err in the PID.

Patch 4-5 are bugs found during Baytrail-T testing
