Do you have any way to separate the VK drivers submission from the
request_partial_firmware_into_buf() work that you are doing? It looks
like it is going to require quite a few iterations of this patch set for
the firmware/fs/IMA part to be ironed out, so if you could get your
driver separated out, it might help you achieve partial success here.
