Custom dCore-buster64 4.19.20 kernel build

[zhudock]

The instructions posted over here http://forum.tinycorelinux.net/index.php/topic,23060.0.html  seem like a solid start to building a custom kernel.

I was hoping to rebuild the dCore-buster64 kernel, jumping from 4.19.10 to 4.19.20, and enabling the IIO modules, so i can read accelerometer and ambient light sensor data. I read that the 4.19.10 build had a bug where building with the IIO modules enabled was still incomplete, and the fix for that was rolled into 4.19.20

I didn't see patched or pre-packaged sources for the 4.19.10 build over here http://tinycorelinux.net/dCore/x86_64/import/src/

Are the devtmpfs changes for bzImage no longer necessary?  Is just the .patch file available so I could merge it into 4.19.20?

Any additional guidance would be much appreciated.
