Bluetooth: Remove assignments in if-statements

2014-03-05T18:52:17Z

Remove assignment in if-statements to be consistent with the coding style. Signed-off-by: Valentin Ilie Signed-off-by: Johan Hedberg

Bluetooth: Declare bfusb_table[] as const

2013-10-11T15:05:20Z

The bfusb_table[] device table can be declared as const Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Remove pointless parameter check in bfusb_send_frame()

2013-10-11T14:52:37Z

The hdev parameter of bfusb_send_frame() is always valid. If it were not valid, then it would have crashed earlier in the call chain. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Add hdev parameter to hdev->send driver callback

2013-10-11T13:28:03Z

Instead of masking hdev inside the skb->dev parameter, hand it directly to the driver as a parameter to hdev->send. This makes the driver interface more clear and simpler. This patch fixes all drivers to accept and handle the new parameter of hdev->send callback. Special care has been taken for bpa10x and btusb drivers that require having skb->dev set to hdev for the URB transmit complete handlers. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Provide hdev parameter to hci_recv_frame() driver callback

2013-10-11T07:45:34Z

To avoid casting skb->dev into hdev, just let the drivers provide the hdev directly when calling hci_recv_frame() function. This patch also fixes up all drivers to provide the hdev. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Remove unused bfusb_ioctl() callback

2013-10-10T20:09:49Z

The bfusb_ioctl() function is not used and thus remove it. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Use devm_kzalloc in bfusb.c file

2012-08-06T18:03:00Z

devm_kzalloc() eliminates the need to free memory explicitly thereby saving some cleanup code. Signed-off-by: Sachin Kamat Acked-by: Marcel Holtmann Signed-off-by: Gustavo Padovan

USB: Disable hub-initiated LPM for comms devices.

2012-05-18T22:42:55Z

Hub-initiated LPM is not good for USB communications devices. Comms devices should be able to tell when their link can go into a lower power state, because they know when an incoming transmission is finished. Ideally, these devices would slam their links into a lower power state, using the device-initiated LPM, after finishing the last packet of their data transfer. If we enable the idle timeouts for the parent hubs to enable hub-initiated LPM, we will get a lot of useless LPM packets on the bus as the devices reject LPM transitions when they're in the middle of receiving data. Worse, some devices might blindly accept the hub-initiated LPM and power down their radios while they're in the middle of receiving a transmission. The Intel Windows folks are disabling hub-initiated LPM for all USB communications devices under a xHCI USB 3.0 host. In order to keep the Linux behavior as close as possible to Windows, we need to do the same in Linux. Set the disable_hub_initiated_lpm flag for for all USB communications drivers. I know there aren't currently any USB 3.0 devices that implement these class specifications, but we should be ready if they do.

Bluetooth: Remove hci_dev->driver_data

2012-02-13T15:01:37Z

The linux device model provides dev_set/get_drvdata so we can use this to save private driver data. This also removes several unnecessary casts. Signed-off-by: David Herrmann Acked-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Remove HCI-owner field

2012-02-13T15:01:24Z

After unregistering an hci_dev object a bluetooth driver does not have any callbacks in the hci_dev structure left over. Therefore, there is no need to keep a reference to the module. Previously, we needed this to protect the hci-destruct callback. However, this callback is no longer available so we do not need this owner field, anymore. Drivers now call hci_unregister_dev() and they are done with the object. Signed-off-by: David Herrmann Acked-by: Marcel Holtmann Signed-off-by: Johan Hedberg
