Only speaking for myself, IANAL, but AFAIK the stand on that is that it
is not acceptable. We do not want any blobs to be loaded into the kernel,
also note that AFAIK most v4l subsystem symbols are exported GPL_ONLY, iow
they are intended only for use by GPL licenses kernel module, so not by blobs.
