I don't get it, just 8 changes? If I do a 'git grep unsigned drivers/media/common/v4l2-tpg'
I get 128 hits, and include/media/tpg/v4l2-tpg.h has another 52.

What's the point of changing just a few of these instances instead of doing
them all?

In any case, patches like this just create a lot of noise and take away too
much code reviewer bandwidth for very little gain.

Speaking for the media subsystem I will reject patches like this, it's not
worth the effort.

Regards,

Hans
