From 0ac3dbf9995281261abecfd2970406dd4e07955b Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Thu, 29 May 2014 15:00:03 +0300 Subject: [PATCH] Bluetooth: Remove unused hci_find_ltk function Now that LTKs are always looked up based on bdaddr (with EDiv/Rand checks done after a successful lookup) the hci_find_ltk function is not needed anymore. This patch removes the function.
