Re: [Patch 3/3] clk: Avoid re-parenting orphan clk's having invalid parent index.

Sorry for not being descriptive in commit message. a) Avoids unnecessary re-parenting cycle for orphan clock's with invalid parent for every clock True, but this is a minor optimisation. If this is a big optimization for you then you really need to fix your bootloader. We
