OK. I'll send v2. Maybe i can change my personal idiom.
I've learned to do this so to avoid a unintended assignment to a variable.
For exmaple:
if (var = 10)
compiler will do assignment to variable.
if (10 = var)
compiler will generate error.

But in these days "checkpatch.pl" will warn in such case.
