Hy, i try to compile this drivers since two day under debian 10 with GCC-10
but there lot, lot of problem like :

so is there any requirement for being to sure to success ?

does anoyone compile this driver whith success on an 5.10.0-18 debian kernel ?

I was able to compile for v5.10.146. I was using GCC 12, though. However, I do not see a reason why GCC 10 wouldn't work anymore.
