So I'm just using a blunt instrument one-liner to request_module the
tfp4 panel driver on module init. This is ugly, and needs testing, etc.
It'll never go upstream. We can perhaps get away with a synchronous
request_module call during module init because that happens in the
context of modprobe (kmod) and so we probably won't deadlock stuff, but
the right thing in general is probably to DECLARE_WORK a worker that can
be scheduled in the kernel at probe time based on what chips are
actually present, e.g. after parsing the devicetree for that data. This
is just stream-of-consciousness thinking here, I'll think more about it.

I'll be ordering some new Panda ES boards for myself and Peter, since
the EB3 and other engineering builds seem to generate a backtrace on
boot. It's not worth fixing that if production ES boards are working.

Jon.
