From e6d465cb482935c26cb4065a6ab9ce987c067da3 Mon Sep 17 00:00:00 2001 From: Andre Guedes Date: Wed, 9 Nov 2011 17:14:26 -0300 Subject: Bluetooth: mgmt_stop_discovery_failed() This patches creates mgmt_stop_discovery_failed() which removes pending MGMT_OP_STOP_DISCOVERY commands and sends proper command status events. This patch also fixes the MGMT_OP_STOP_DISCOVERY command leak in case cancel inquiry fails. Signed-off-by: Andre Guedes Acked-by: Marcel Holtmann Signed-off-by: Gustavo F.
