cxd2843: i2c_write error adr 6c data 00

[bon-the-one]

Hi Marcus,
Thanks for your work on these drivers. Really appreciated. Owe you MUCH beer!
I tried building them for Kernel 4.17, but no go. So I installed a virtual machine, running 4.10 and mapped over the PCI. The drivers built and run show up in lsmod (I'm using the forked version for my DVB-T2 tuners on a BGT3600 by the way). I can see the DVB-S frontends fine, but the DVB-T tuners have no front end showing up in /dev/dvb/adaptorX (where X is either DVB-T tuner).
Looking at the start up log, in dmesg, I see ...

I'm guessing this is because I'm using Virtualbox, but just in case have you seen it before? My machine is a Ryzen 2400G build, with 4.17 as the host machine (Ubuntu Mint 18.04) and the guest is Ubuntu Server 16.04 using kernel 4.10.
I need kernel 4.17 to use my Ryzen 'properly' so I was wondering if you were planning to update for that kernel, or if there was a way you know for me to fix the error in 4.10 on VirtualB?
Thank again,
Ian

A lot has changed in 4.17 - basically making these drivers need a re-write.
My objectives where to keep making small mods as and when the kernel required it. The changes made in 4.17 mean that I'll not be able to update!

driver dont need a rewrite it just there two lot of drivers as the kernel install driver to a diffrent place that the bgt drivers install you just need to move out the kernel driver that stopping these diver from working

Glad someone has continued my work.
I don't have any BGT hardware anymore due to continued hardware quality issues and lack of any support from the manufacturer

[cbtrident]

it a shame you did not ask or say about the quality issues as i could have help you to sort out
what the quality issues you was having at the time

Hardware dropouts across multiple adapters.
I've moved to the much better made (and support ed) TBS range.
