As an update to my last post - I recompiled all 5 patches in an LE 8 build and everything looks good. Both tuners show up and are working. Other usb tuners were not impacted. I was just recording 3 streams on 2 usb devices (2 streams on WinTV-DualHD and 1 on a Kworld-435Q) all running an RPi 3 and everything was smooth.
I believe these patches will be good until the driver is added into the mainline linux kernel.
Awesome edit4ever, sorry I've been gone for the past week. I never got to compile the patch, but it sounds like you have a working build. I'm happy to test it on the RPi3 if it's around. Otherwise I'll wait to see it in an update or maybe try to refresh my git pull and build again.
