Hi,
This patch is already on upstream. Unfortunately, previous backports
of related commits caused some issues so just skipping this one isn't
a good option.
For module parameters, while it's quite unrealistic for users to have
more than one identical keyboard but with different firmware, this is
possible and having a module option would prevent tuning only specific
keyboard.
For the documentation, makes sense. Sorry, I should have done it
together with the change, I'll fix it, thanks for pointing it out.
