What I am proposing isn't a workaround, it is a fundamental part of
the solution, and it is even the approach which requires the minimum
amount of changes. This is as straightforward a solution as you can
hope for.

I do not plan to add any hook. The plan is to instantiate all IR
devices we know are present, and let ir-kbd-i2c bind to the ones it
supports. The fact that another out-of-tree driver may optionally bind
to these devices is a side effect.

I would love to say "let's just ignore lirc altogether", however 1* I
don't think it makes any sense to break user systems when it is trivial
for us to not break them and 2* I don't think it is smart to be rude
with lirc developers are the exact moment they decide to attempt to
merge their drivers in the kernel tree.

Yes, this is my understanding as well.

Will this happen next week? I fear not. Which is why I can't wait for
it. And anyway, in order to merge the lirc_i2c driver, it must be
turned into a new-style I2C driver first, so bridge drivers must be
prepared for this, which is _exactly_ what my patches are doing.
