linux-next: build failure in the final build

[Mark Brown]

Hi all,

In the final builds, today's linux-next build (arm64 allyesconfig)
failed like this:

cc1: all warnings being treated as errors make[6]:

It looks like this is a change in dependencies which has allowed this to
be built from today, I didn't isolate exactly what - it looks like the
issue is missing statics on all these function definitions, making them
global.  I have ignored this for today.
