Hello, for hid-bigbenff, I used the code of hid-betopff and hid-sony to learn about writing a device driver. Benjamin's review of hid-bigbenff noted that one should use the devm_ api calls these days, which served as a motivation to refactor this api change into the older code where appropriate. This removes some device teardown code and makes error handling easier. I tested this with a Sony Dualshock 3 bluetooth gamepad only, so additional test reports from other users of the driver may be warranted.
