It generally looks good to me although it's a bit unusual to use devres on device. Given the way input_dev is used, it probably makes sense, I guess. One thing tho. If possible and there aren't too many, wouldn't it be better to convert all to use devres. Having two different lifetime fules tends to lead to gotchas.
