When closing a namespace a } is sufficient. It doesn't need to be }; like closing a class or enum. Within frameworks/base/libs/hwui there is a mix between } and }; when closing a namespace. There are even mixes between a .h and the corresponding .cpp files. In a separate CL I was asked to not close with };. That was a good comment. I adopted the style from nearby code. This CL cleans up the nearby code. Test: I made sure the code still built as expected. Change-Id: Ieb314a4f48d6e33752463f3be4361fdc9be97482
