Bluetooth: Move handling of HCI_RUNNING flag into core

2015-10-05T07:30:25+00:00

Setting and clearing of HCI_RUNNING flag in each and every driver is
just duplicating the same code all over the place. So instead of having
the driver do it in their hdev->open and hdev->close callbacks, set it
globally in the core transport handling.

Bluetooth: Move HCI_RUNNING check into hci_send_frame

2015-10-05T07:30:10+00:00

In all callbacks for hdev->send the status of HCI_RUNNING is checked. So
instead of repeating that code in every driver, move the check into the
hci_send_frame function before calling hdev->send.

Bluetooth: btwilink: remove DEBUG define

2015-05-13T21:00:51+00:00

Remove the DEBUG define as the debug code; so can remove mass debug info
from log buffer when using dmesg.

bluetooth: drop owner assignment from platform_drivers

2014-10-20T14:20:19+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

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

2013-10-11T13:28:03+00:00

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.

Bluetooth: Provide hdev parameter to hci_recv_frame() driver callback

2013-10-11T07:45:34+00:00

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.

Bluetooth: Use module_platform_driver() in btwilink.c file

2012-09-08T19:53:47+00:00

module_platform_driver() makes the code simpler by eliminating module_init
and module_exit calls.

Bluetooth: Use devm_kzalloc in btwilink.c file

2012-08-06T18:03:02+00:00

devm_kzalloc() eliminates the need to free memory explicitly
thereby saving some cleanup code.

Bluetooth: Remove hci_dev->driver_data

2012-02-13T15:01:37+00:00

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.

Bluetooth: Remove HCI-owner field

2012-02-13T15:01:24+00:00

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.
