From 7776d1d8051469e61c8784076921ee16c1093ba1 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Fri, 5 Dec 2014 13:36:03 +0200 Subject: [PATCH] Bluetooth: Use cmd_complete callback for authentication mgmt commands This patch converts the user confirmation & PIN code mgmt commands to take advantage of the new cmd_complete callback for pending mgmt commands. The patch also adds a new generic addr_cmd_complete() helper function to be used with commands that send a mgmt_addr_info response based on a mgmt_addr_info in the beginning of the command parameters.
