Subject: [PATCH] Bluetooth: hci_sysfs: make bt_class a static const structure

From: Ivan Orlov <[email protected]>

Now that the driver core allows for struct class to be in read-only
memory, move the bt_class structure to be declared at build time
placing it into read-only memory, instead of having to be dynamically
allocated at load time.
