Hello! I was not sure who or what to reach out to with this question, so I'm hoping this lands in the hands of the correct person. I've been using Yocto for many years for our ARM embedded system builds, and have recently upgraded our kernel version from 4.18 to 5.1 (details below). I am working on patching now, and getting our out-of-tree modules ported to build with the 5.1 kernel source. I'm able to build the kernel using bitbake virtual/kernel, and boot the kernel + dtb no problem, however, my kernel's out-of-tree modules are having trouble building for reasons that I cannot seem to figure out. I have a very simple kernel module, called a10id-kmod that I'm trying to build. Forgive me if this is not the correct information to send over, this is my first time seeking support and am not sure what to send, happy to send any additional logs needed. The bitbake output shows the following:
