Installing an in-tree driver for a DSI display panel

Hey @lowder, can you try again with the gcc-10 branch of the kernel-module-build project?
https://github.com/balena-os/kernel-module-build/tree/gcc-10

Also make sure to use the correct device raspberrypicm4-ioboard when building the module as the latest OS for raspberrypi4-64 is on a newer kernel and will not be compatible.

There’s a similar question here in case some of your module build issues have already been answered:

Error when compiling kernel module in the kernel module build example

@jleppert This works for me using the gcc-10 branch. I even used raspberrypicm4-ioboard and 2.71.3+rev5 to be sure. Can you confirm from the top of your build log that gcc-10 is being installed?
