Thank you for the patch, I have applied it to the kernel sources but I'm
not sure how to proceed from now on. Should I compile the whole kernel or

You need to build the whole kernel, install and reboot.

Thanks, it's compiling now, I'll take it for a test drive once it is
done
and installed and provide you with a dmesg log.
