Subject: linux-next: build failure after merge of the etnaviv tree

Hi Lucas,

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

drivers/gpu/drm/tve200/Kconfig:1:error: recursive dependency detected!

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.
