2013-10-11Bluetooth: Remove pointless parameter check in btmrvl_send_frame()Marcel Holtmann
The hdev parameter of btmrvl_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 <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-11Bluetooth: Add hdev parameter to hdev->send driver callbackMarcel Holtmann
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.

2013-06-13Bluetooth: btmrvl: fix thread stopping raceDaniel Drake
There is currently a race condition in the btmrvl_remove_card() which is causing hangs on suspend for OLPC. When the race occurs, kthread_stop() never returns. The problem is that btmrvl_service_main_thread() calls kthread_should_stop() and then does a fair number of things before restarting the loop and sleeping. If the thread gets stopped after kthread_should_stop() is checked, but before the sleep happens, the thread will go to sleep and won't necessarily be woken up. Move the kthread_should_stop() check into a race-free place. Signed-off-by: Daniel Drake <dsd@laptop.org> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Signed-off-by: John W.

2012-05-09Bluetooth: btmrvl: configure default host sleep parametersAmitkumar Karwar
Currently debugfs commands "hscfgcmd" and "gpiogap" are provided for host sleep configuration. But if user doesn't configure host sleep parameters using these commands, host sleep activation is failed during suspend (support for suspend and resume handlers is added in next patch). Default host sleep configuration is done during driver initialisation in this patch.

2012-02-13Bluetooth: Remove hci_dev->driver_dataDavid Herrmann
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.

2012-02-13Bluetooth: Remove HCI-owner fieldDavid Herrmann
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.

2011-11-21freezer: don't unnecessarily set PF_NOFREEZE explicitlyTejun Heo
Some drivers set PF_NOFREEZE in their kthread functions which is completely unnecessary and racy - some part of freezer code doesn't consider cases where PF_NOFREEZE is set asynchronous to freezer operations. In general, there's no reason to allow setting PF_NOFREEZE explicitly. Remove them and change the documentation to note that setting PF_NOFREEZE directly isn't allowed. -v2: Dropped change to twl4030-irq.c as it no longer uses PF_NOFREEZE.

2010-07-21Bluetooth: Process interrupt in main thread of btmrvl driver as wellAmitkumar Karwar
When driver is sending a command or data and the firmware is also sending a sleep event, sometimes it is observed that driver will continue to send the command/data to firmware right after processing sleep event. Once sleep event is processed driver is not supposed to send anything because firmware is in sleep state after that. Previously interrupt processing was done in SDIO interrupt callback handler. Now it is done in btmrvl driver main thread to solve the cross-sending properly.
