On the things I have on my plate, I'll try to remove all of the tiny HID drivers that does nothing but some small remapping. This will probably need help from userspace ("firmware" or bpf loading), and I have not settled my plans yet. I also think we should probably clean up the Kconfig now that hid-generic can unbind itself if there is a special driver coming in. And that means that we should probably start removing the blacklist of devices that have special modules, to let them be taken by hid-generic on boot until their driver is loaded. > > That being said, benff Kconfig setting definitely escaped attention.

Not sure I have actually reviewed this one (I don't think so), but I'll keep this in my head for next drivers. Cheers, Benjamin > > Thanks, > > -- > Jiri Kosina > SUSE Labs >
