Do you have a backported version of this series that will apply to that
kernel tree?  If so, I'll be glad to apply it but I'm pretty sure the
reason I did not apply them was because they did not apply correctly.

Also, are you even sure you need these patches for 3.18.y?  Do you have
a v4l2 device that relies on these fixes?

thanks,
