Bluetooth: hci_intel: Fix null gpio desc pointer dereference

2016-08-20T16:09:17+00:00

commit 32b9ccbc3522811c0e483637b85ae25f5491296f upstream. gpiod_get_optional can return either ERR_PTR or NULL pointer. NULL case is not tested and then dereferenced later in desc_to_gpio. Fix this by using non optional version which returns ERR_PTR in any error case (this is not an optional gpio). Use the same non optional version for the host-wake gpio.

Bluetooth: hci_uart: Provide initial manufacturer information

2015-10-21T04:20:44+00:00

Provide an early indication about the manufacturer information so that it can be forwarded into monitor channel. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: btintel: Add support for enabling tracing functionality

2015-10-20T22:49:21+00:00

For Intel controllers with firmware that allows tracing of baseband functionality this allows enabling it via set_diag driver callback. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: hci_intel: Cleanup the device probe code

2015-10-01T06:55:42+00:00

There is some unneeded code in "hci_intel" probing. First acpi_match_device() call is needless as driver/platform/acpi core code has already done the matching before calling the probe and the driver does not use the returned pointer to matching _HID other than checking is it NULL. Then tree wide grep for "hci_intel" doesn't reveal that there is any code registering this platform device so it looks this device is always backed with ACPI companion so also ACPI_HANDLE() test can be removed.

Bluetooth: hci_intel: Enable IRQ wake capability

2015-09-17T11:20:06+00:00

We need to explicitly enable the IRQ wakeup mode to let the controller wake the system from sleep states (like suspend-to-ram). PM suspend/resume callbacks now call the generic intel device PM functions after enabling/disabling IRQ wake. Signed-off-by: Loic Poulain Signed-off-by: Marcel Holtmann

Bluetooth: hci_intel: Give priority to LPM packets

2015-09-17T11:20:06+00:00

Change the way to insert LPM packets into the txq. Use skb_queue_head instead of skb_queue_tail to always prioritise LPM packets over potential tx queue content. Signed-off-by: Loic Poulain Signed-off-by: Marcel Holtmann

Bluetooth: hci_intel: Add Device configuration

2015-09-17T11:20:05+00:00

Apply DDC parameters once controller is in operational mode. Signed-off-by: Loic Poulain Signed-off-by: Marcel Holtmann

Bluetooth: hci_intel: Fix warnings due to unused lpm functions

2015-09-17T11:20:05+00:00

intel_lpm_suspend/resume are only used in case of CONFIG_PM. Signed-off-by: Loic Poulain Signed-off-by: Marcel Holtmann

Bluetooth: hci_intel: Show error in case of invalid LPM packet size

2015-09-17T11:20:02+00:00

Don't hide this packet size error. Signed-off-by: Loic Poulain Signed-off-by: Marcel Holtmann

Bluetooth: hci_intel: Add runtime PM support

2015-09-17T11:20:02+00:00

Implement runtime PM suspend/resume callbacks. If LPM supported, controller is put into supsend after a delay of inactivity (1s). Inactivity is based on LPM idle notification and host TX traffic. Signed-off-by: Loic Poulain Signed-off-by: Marcel Holtmann
