Hi Mark,

Thanks for you comments. I'll split it to 3 patches:
- abstract locking out into helper functions;
- introduce regulator chain locking scheme
- allow reentrant calls into the regulator framework (with hope that is 
has future,
may be can enable/disable it through constraints)

I understand that Regulator FW is common and wide used and we should 
very careful here.
