From 952497b159468477392f9b562b904da9bc76d468 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Thu, 18 Jun 2015 21:05:31 +0300 Subject: [PATCH] Bluetooth: Fix warning of potentially uninitialized adv_instance variable Rework the logic of checking for a valid adv_instance for non-zero cp->instance values. Without this change we may get (false positive) warnings as follows: >> net/bluetooth/mgmt.c:7294:29: warning: 'adv_instance' may be used uninitialized in this function [-Wuninitialized] Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann --- net/bluetooth/mgmt.c | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) diff --git a/net/bluetooth/mgmt.c b/net/bluetooth/mgmt.c index 2fe6f3bfc579..7998fb279165 100644 --- a/net/bluetooth/mgmt.c +++ b/net/bluetooth/mgmt.c @@ -7280,19 +7280,15 @@ static int remove_advertising(struct sock *sk, struct hci_dev *hdev, { struct mgmt_cp_remove_advertising *cp = data; struct mgmt_rp_remove_advertising rp; - struct adv_info *adv_instance; - int err; struct mgmt_pending_cmd *cmd; struct hci_request req; + int err; BT_DBG("%s", hdev->name); hci_dev_lock(hdev); - if (cp->instance) - adv_instance = hci_find_adv_instance(hdev, cp->instance); - - if (!(cp->instance == 0x00 || adv_instance)) { + if (cp->instance && !hci_find_adv_instance(hdev, cp->instance)) { err = mgmt_cmd_status(sk, hdev->id, MGMT_OP_REMOVE_ADVERTISING, MGMT_STATUS_INVALID_PARAMS); -- 2.20.1
