From 4518bb0fb5eda46a9b118a6fbd9661e62a34a5b6 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Mon, 24 Feb 2014 20:35:07 +0200 Subject: [PATCH] Bluetooth: Fix canceling RPA expiry timer The RPA expiry timer is only initialized inside mgmt.c when we receive the first command from user space. This action also involves setting the HCI_MGMT flag for the first time so that flag acts as a good indicator of whether the delayed work variable can be touched or not. This patch fixes hci_dev_do_close to first check the flag.
