If you wanted to use the uninitialized_var() macro for a pointer,
the trick is:

	struct binder_buffer *uninitialized_var(buffer);

But this is fine as is.

The subject should have a subsystem prefix.  You'll need to resend
both patches for that reason.  (You had them correct in the original
version you sent to kj).  The subjects could also say [patch 1/2]
and [patch 2/2] but it doesn't matter since the line numbers didn't
change and they can be applied in any order.

Don't forget to CC Greg.  He reads the list as well, but you should
always CC a maintainer and a list for each patch.

Anyway, it looks good.  Just fix the subjects and resend.  When you
resend a patch it should say [patch 1/2 v2] in the subject and below
the signed off by line put:
---
v2: added a subsystem prefix to the subject

Sorry that it's a lot of nit picky work.  We have to push as much
work as we can on to patch submitters so that maintainers can apply
things with a click of the mouse.  After a while you'll learn all
the rules.  :)
