[PATCH 0/9] staging: bcm2835-audio: Cleanups and upgrades

Hi,

I just received a RPi3B+ and decided to have a go at fixing stuff in
the audio driver:

The first half of the patchset are just random fixes found while reading
the code.

The second half provides devicetree bindings for bcm2835-audio and fixes
the probe sequence so it fails gracefully if VCHIQ isn't there (as per
TODO).

The series was developed on top of linux-next and tested on a RPi2B and
RPi3B+. Sadly I don't have an HDMI monitor with sound so I only tested
the mini jack output.

Thanks,
Nicolas
