[ Upstream commit a254b90c9aac3d3d938a07e019773e35a977451b ]
This fixes the master BIS cleanup procedure - as opposed to CIS cleanup, no HCI disconnect command should be issued. A master BIS should only be terminated by disabling periodic and extended advertising, and terminating the BIG.
In case of a Broadcast Receiver, all BIS and PA connections can be cleaned up by calling hci_conn_failed, since it contains all function calls that are necessary for successful cleanup.

[ Upstream commit 9c16d0c8d93e3d2a95c5ed927b061f244db75579 ]
ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove().
Note that the upper limit of ida_simple_get() is exclusive, but the one of ida_alloc_max() is inclusive. So a -1 has been added when needed.

Since BT_HS has been remove HCI_AMP controllers no longer has any use so remove it along with the capability of creating AMP controllers.
Since we no longer need to differentiate between AMP and Primary controllers, as only HCI_PRIMARY is left, this also remove hdev->dev_type altogether.

mainline inclusion from mainline-v6.10-rc4 commit c695439d198d30e10553a3b98360c5efe77b6903 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IA6ZJK CVE: CVE-2024-38620
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
--------------------------------
The amp_id argument of l2cap_connect() was removed in commit 84a4bb6548a2 ("Bluetooth: HCI: Remove HCI_AMP support")
It was always called with amp_id == 0, i.e. AMP_ID_BREDR == 0x00 (ie. non-AMP controller). In the above commit, the code path for amp_id != 0 was preserved, although it should have used the amp_id == 0 one.
Restore the previous behavior of the non-AMP code path, to fix problems with L2CAP connections.
