devm_kzalloc is a device managed function and makes code a bit
smaller and cleaner.

This patch is based on Mauro's re-organized tree
(media_tree staging/for_v3.7) and is compile tested.

I think the same should be done to sensor->nvm. Would you like to change the
patch to incorporate the change? I'm fine doing that as well.

Sure. I will send the updated patch shortly. I have also expanded the
scope of the patch to
