Matias Karhumaa 09b6c08061 Bluetooth: Fix debugfs NULL pointer dereference ... [ Upstream commit 30d65e0804 ] Fix crash caused by NULL pointer dereference when debugfs functions le_max_key_read, le_max_key_size_write, le_min_key_size_read or le_min_key_size_write and Bluetooth adapter was powered off. Fix is to move max_key_size and min_key_size from smp_dev to hci_dev. At the same time they were renamed to le_max_key_size and le_min_key_size.
