6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>
[ Upstream commit 50efc63d1a7a7b9a6ed21adae1b9a7123ec8abc0 ]
hci_conn_hash_lookup_cis shall always match the requested CIG and CIS
ids even when they are unset as otherwise it result in not being able
to bind/connect different sockets to the same address as that would
result in having multiple sockets mapping to the same hci_conn which
doesn't really work and prevents BAP audio configuration such as
AC 6(i) when CIG and CIS are left unset.
Fixes: c14516faede3 ("Bluetooth: hci_conn: Fix not matching by CIS ID")
