Ah, thanks. Same issues there in

cinergyt2_frontend_attach()
cinergyt2_rc_query()

I think this would require more in-depth review of all the media drivers
and having all this fixed for 4.9. It should be pretty straightforward;
all the instances I've seen so far should be just straightforward
conversion to kmalloc() + kfree(), as the buffer is not being embedded in
any structure etc.
