Personally I won't prefer such stand-alone cleanup  _unless_ there is
major driver re-write of the code, because this breaks the traceability
via 'git blame'. And even in that case, this change should be applied first,
and the other functional updates later.

On same lines, I was trying to clean-up omap2.c driver with
s/info->nand\./nand_chip->/
But withheld it till the point when I had to almost re-write complete probe.
So, I first did this change, and then on top-of-it re-wrote the omap_nand_probe().
