[PATCH][RFC] Removing wrong judgement of checkpatch.pl for returnas function

From: Hitoshi Mitake

I found a strange behaviour of checkpatch.pl.

The C statement:
return (type)value;
is regarded as return like a function form by checkpatch.pl.
So checkpatch.pl causes "Return is not a function." error
when processing statements like this.

I think statements like above are innocence. These are only doing type cast.
This patch removes the behaviour of checkpatch.pl.

But I don't have confidence about coding style of Linux kernel.
Is my thought correct? Or the behaviour of current checkpatch.pl is correct?
Request for comment.
