Hi Linus, As a general comment: I don't see that much here that warrants putting all of this into the kernel driver. Given the bits I've seen from openrazer, there is quite a struggle to get things to work on all devices correctly, so there's a high chance that a) this won't work on the devices and b) that you're locking yourself into an API that cannot be supported on next year's device. so let's count this as a +1 to Benjamin and Luca's comments. Cheers, Peter On Wed, Nov 28, 2018 at 11:24:43PM +0100, Linus Walleij wrote: > The Razer gaming accessories are a pretty popular keyboard > brand.
