No, it's 4.19. It's always a LTS kernel.

I'm curious, what's the motivation behind this? The rpi tree contains
additional hacks, so i'm not sure the results are comparable. Also the
USB host driver is a different one.

Since enabling lan78xx for Raspberry Pi 3B+, we found a lot of driver
issues. So i'm not really surprised, that there are still more of them.

Thanks Stefan
