Driver in kernel >5.4 possible? Tainted kernel 5.7

[raeschenzentrum]

Driver compiles in kernel 5.7 but while loading is tainting the kernel. Is it even possible to use the Driver with kernel > 5.4?

The new release/tn40xx-004 branch includes the fix for kernel 5.7 and supports 5.4 and newer. Tested on Fedora 31 with 5.7.15-100.
