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.
