[U-Boot] [PATCH v3 0/8] Clean-up: squash lines for immediate return

[Masahiro Yamada]

ret = [expression];
if (ret)
        return ret;

return 0;

...  is equivalent to:

return [expression];

First, I sent a tree-wide patch:
http://patchwork.ozlabs.org/patch/665199/

In the review of v1, Stephen suggested that
twee-wide conversion with something like Coccinelle
can break code uniformity.
I took a closer look once again, I found many hunks
we should not change.

So, here is an updated series.

I limited this refactoring to cases, I think, really
beneficial.
(Mostly, they well be simple wrappers with this series.)

I also split patches per-subsystem
for easier review and Acked-by
(or NACK if reviewers found no good reason to change).
