Subject: Re: [PATCH] staging: r8188eu: Remove unnecessary ret variable in
 rtw_drv_init()

To be honest, I prefered the original.

	foo = alloc();
	if (!foo) {
		ret = -EWHATEVER;
		goto free_last_thing;
	}

I like this style of error handling because all the information is
there.  You don't need to scroll down.

I don't really care about this specific patch at all.  It's a small
thing.  But we had someone come through who was sort of obsessed with
removing these sorts of variables.  Just because you can remove a
variable doesn't necessarily make the code more readable.

If you're doing the work and maintaining the driver you get to choose
your own style to some extent.  But I don't want to encourage people to
start sending these sort of patches more generally.
