Subject: [PATCH 00/16] staging: vchiq: dead code removal & misc fixes

Hi All,

This series was written in parallel with reading and understanding the
vchiq code. So excuse me for the lack of logic in the sequence of
patches.

The main focus was to delete as much code as possible, I've counted
around 550 lines, which is not bad. Apart from that there are some
patches enforcing proper kernel APIs usage.

The only patch that really changes code is the
vchiq_ioc_copy_element_data() rewrite.

The last commit updates the TODO list with some of my observations, I
realise some of the might be a little opinionated. If anything it's
going to force a discussion on the topic, which is nice.

It was developed on top of the latest linux-next, and was tested on a
RPIv3B+ with audio, video and running vchiq_test.

Regards,
Nicolas
