Bluetooth: btusb, hci_intel: Fix wait_on_bit_timeout() return value checks

2016-09-19T18:19:34+00:00

wait_on_bit_timeout() returns one of the following three values:
* 0 to indicate success.
* -EINTR to indicate that a signal has been received;
* -EAGAIN to indicate timeout;
Make the wait_on_bit_timeout() callers check for these values.

Bluetooth: hci_intel: Remove LPM enabling from setup procedure

2016-07-11T19:57:50+00:00

LPM can be enabled via a DDC write command at specific DDC ID.
As any other DDC value, this is up to the DDC config file to
include (or not) the low power mode configuration.

Bluetooth: hci_intel: Fix null gpio desc pointer dereference

2016-05-02T17:29:31+00:00

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: btintel: Create common Intel Version Read function

2015-12-09T23:51:51+00:00

The Intel Version Read command is used to retrieve information
about hardware and firmware version/revision of Intel Bluetooth
controllers. This is an Intel generic command used in USB and
UART drivers.

Bluetooth: hci_intel: Use shorter timeout for HCI commands

2015-12-09T23:51:50+00:00

Use the standard HCI_CMD_TIMEOUT(1s) for HCI command instead of
HCI_INIT_TIMEOUT(10s) which is not justified in these cases.

Bluetooth: Use new hci_skb_pkt_* wrappers for drivers

2015-11-19T16:50:27+00:00

The new hci_skb_pkt_* wrappers are mainly intented for drivers to
require less knowledge about bt_cb(sbk) handling. So after converting
the core packet handling, convert all drivers.

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.
