From 33e38b3e13e313baedd7c56c38ad249f230171d2 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Fri, 15 Mar 2013 17:07:05 -0500 Subject: [PATCH] Bluetooth: Fix fast connectable response sending The mgmt_set_fast_connectable response should be sent only when all related HCI commands have completed. This patch fixes the issue by using an async request and sending the response to user space throught the complete callback of the request. The patch also fixes in the same go the return parameters of the command which should be the current settings.
