Hi Lucas,

After merging the etnaviv tree, today's linux-next build (x86_64
allmodconfig) failed like this:

Caused by commit

  dba536cd9538 ("drm/etnaviv: add THERMAL dependency")

I got the abobe warnings while doing "make allmodconfig" and then the
error when doing the actual build.

I have used the etnaviv tree from next-20171127 for today.
