Do you need the request_firmware patch for > 3.16?? Are you seeing problems there. 3.16 doesn't > have b89193e0b06f 3.16.3 has two issues: - 6eb5e3399e8 "em28xx-dvb - fix em28xx_dvb_resume() to not unregister i2c and dvb" is not in 3.16.3 - the request_firmware issue Locally I applied 6eb5e3399e8 and my dvb_frontend_resume() change, which improves it but it is not fully working.

I have to unload and reload the em28xx modules to recover. So it would be good to have an xc5000 patch backport from you instead of my dvb_frontend_resume() change.
