Hemant Gupta b24c62471c Bluetooth: Fix clearing discovery type when stopping discovery
This patch prevents resetting of discovery type while stopping
discovery, since otherwise the wrong type might be send in case of
discovery failure. It also doesn't matter that we are "lazy" with
updating the type since it is anyway reset when starting discovery again
and it's not needed to know the current discovery state.

Marcel Holtmann 053262dce5 Bluetooth: Update management interface revision
For each kernel release where commands or events are added to the
management interface, the revision field should be increment by one.

The increment should only happen once per kernel release and not
for every command/event that gets added. The revision value is for
informational purposes only, but this simple policy would make any
future debugging a lot simple.

David Herrmann 6935e0f518 Bluetooth: Remove redundant hdev->parent field
We initialize the "struct device" in hci_alloc_dev() for a long time now
so we can access hdev->dev.parent directly. Hence, we can drop the
temporary field hdev->parent which is used in no other place than
hci_add_sysfs().

SET_HCIDEV_DEV() is never called after registering a device by the
drivers so we do not overwrite internal device-state. Furthermore,
hdev->dev is initialized to 0 by kzalloc() inside hci_alloc_dev() so the
default behavior with dev.parent = NULL is kept.

Section 9.23.3.5 of IEEE 80211s standard describes the protection rules for

non-HT mixed mode - is selected if any non-HT peers are present in our MBSS.
20MHz-protection mode - is selected if all peers in our 20/40MHz MBSS support
			HT and atleast one HT20 peer is present.
no-protection mode - is selected otherwise.

This is a limited implementation of 9.23.3.5, which only considers mesh peers
when determining the HT protection mode. Station's channel_type needs to be
maintained.
