Issue during do_rootfs for custom kernel modules

Issue during do_rootfs for custom kernel modules

Hi,

I am trying to build a custom kernel module for a marvell wifi/BT module and am running into a strange error during the rootfs step.

Problem: conflicting requests
- nothing provides kernel-module-bt8977-4.9.88-cl-som-imx8-6.9+g5e23f9d61147 needed by kernel-module-marvell-bt8977-1.0-r0.cl_som_imx8
ERROR: patroness-image-1.0-r0 do_rootfs: Function failed: do_rootfs
ERROR: Logfile of failure stored in: /home/build/compulab-rocko/build-wayland/tmp/work/cl_som_imx8-poky-linux/patroness-image/1.0-r0/temp/log.do_rootfs.25346
ERROR: Task (/home/build/compulab-rocko/sources/meta-patroness/recipes-core/images/patroness-image.bb:do_rootfs) failed with exit code '1'

I have checked the attached logfile and it does not seem to have anymore information about what would be causing this issue.

I cannot figure out why it cannot find the kernel-module-bt8977-4.9.88-cl-som-imx8-6.9+g5e23f9d61147 package since it shows up in the package folder in build-wayland/tmp/work/cl_som_imx8-poky-linux/kernel-module-marvell-bt8977/1.0-r0

I have also attached the bitbake recipe for this module but it does not seem to set the version for this anywhere.

Does anyone have an idea of what might be causing this or where I should continue investigating this failure?

Thanks,
