Patch: V4L stable versions 4.5.3 and 4.5.4

[David R]

Hi

Please consider applying the attached patch (or something like it) to
V4L2, and whatever is appropriate to the mainstream kernel. Without this
my media server crashes and burns at boot.

See https://lkml.org/lkml/2016/5/7/88 for more details

Thanks
David
