From 9d4c1cc15b14b4a96ddfcfac533a12f9f527c129 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 21 Oct 2015 18:03:01 +0300 Subject: [PATCH] Bluetooth: Use hci_conn_hash_lookup_le() when possible Use the new hci_conn_hash_lookup_le() API to look up LE connections. This way we're guaranteed exact matches that also take into account the address type.
