Errors building in 4.14.15: dmx_* undeclared

[OJFord]

Many thanks for your work on this!

Unfortunately there are some issues building with the latest kernel:

try driver from this git http://git.cblinux.co.uk:5010/Blackgold/BGT3xxx-fork-for-cxd2837

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

Thanks @cbtrident, BlackGold support actually pointed me to the same, I haven't got around to trying it though.
