There is time. I just merged this series today.

The thing is that we currently have few developers working on
DVB, and no sub-maintainers. Due to that, I need to review
them myself, with I usually do after reviewing/applying patches
from sub-maintainers.

Yeah, it would be great if Ralph would have some time to review
them, or to submit a new series adding all pending features from
DD drivers upstream.

Both Jasmin and Thomas could have reviewed it, and replied
if they tested it, and on what conditions. I tend to give
people some time to review/test patches, before doing my
review, as I don't usually have time for testing everything
myself.

Hans is focused at V4L2 side.

Btw, while you're here, it would be great if you could take
a look on those warnings (that comes via smatch):

	drivers/media/pci/ddbridge/ddbridge-core.c:1009 input_tasklet() warn: this loop depends on readl() succeeding
	drivers/media/pci/ddbridge/ddbridge-core.c:1353 flashio() warn: this loop depends on readl() succeeding
	drivers/media/pci/ddbridge/ddbridge-core.c:1373 flashio() warn: this loop depends on readl() succeeding
