4.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Todd Kjos <tk...@android.com>
commit 8ca86f1639ec5890d400fff9211aca22d0a392eb upstream.
The format specifier "%p" can leak kernel addresses. Use
"%pK" instead. There were 4 remaining cases in binder.c.
