Bartosz Golaszewski 09d6efc6ab reset: gpio: suppress bind attributes in sysfs
[ Upstream commit 16de4c6a8f ]

This is a special device that's created dynamically and is supposed to
stay in memory forever. We also currently don't have a devlink between
it and the actual reset consumer. Suppress sysfs bind attributes so that
user-space can't unbind the device because - as of now - it will cause a
use-after-free splat from any user that puts the reset control handle.
