Yes, I'm aware of that. I'm doing the conversion of drivers under dvb-usb, at: https://git.linuxtv.org/mchehab/experimental.git/log/?h=media_dmastack_fixes I'll be sending the patches to the ML after ready. I'll then take a look on other USB drivers that use the stack. I guess the non-USB media drivers are safe from this issue.
