Commitd9fb3754ec("greybus: loopback: Relax locking during loopback operations") changes the holding of the per-connection mutex to be less restrictive because at the time of that commit per-connection mutexes were encapsulated by a per-driver level gb_dev.mutex. Commit8e1d6c336d("greybus: loopback: drop bus aggregate calculation") on the other hand subtracts the driver level gb_dev.mutex but neglects to move the mutex back to the place it was prior to commitd9fb3754ec("greybus: loopback: Relax locking during loopback operations"), as a result several members of the per connection struct gb_loopback are racy. The solution is restoring the old location of mutex_unlock(&gb->mutex) as it was in commitd9fb3754ec("greybus: loopback: Relax locking during loopback operations").
