6909X - Compile Issues

[Krobaruk]

I'm trying to build the stid135 module from source because I think the mutex fixes from a commit 2 days ago could really help me. I'm using Arch Linux with this kernel:
5.0.10-arch1-1-ARCH

I'm running this from the media_build directory:
./build --main-git --depth 1

The errors are:
******************

I have the Kernel headers installed but it seems more recent kernels have removed the cx25821 files it is trying to patch. Any ideas how I can make this work?

Deleting the media_build folder and starting again seemed to fix it. Crazycat mentioned a few months ago that kernel at least as high as 5.0.x work fine.
