[ Upstream commit cc4f952427aaa44ecfd92542e10a65cce67bd6f4 ]
When a force feedback command is sent from userspace, work is scheduled to pass this data to the controller without blocking userspace itself. However, in theory, this work might not be properly canceled if the controller is removed at the exact right time. This patch ensures the work is properly canceled when the device is removed.
