The linux-media policy is to have zero warnings with W=1. However, when
I started using a Jenkins instance at https://builder.linuxtv.org to automate
such tests, I didn't notice that a bug at the scripts were just ignoring
warnings.

Now that this is fixed, we need to get rid of the warnings that got
re-introduced when the atomisp driver was reverted, as otherwise,
every time a common header is touched, we'll see messages like
those:
