Marcel Holtmann 2eda66f4a0 Bluetooth: Add fine grained mem_flags usage to btusb driver
The URB submission routines need more fine grained control for the
mem_flags used by kmalloc(), usb_alloc_urb() and usb_submit_urb() to
better support different caller situations. Add a mem_flags parameter
and give the caller full control.

Marcel Holtmann 1305e9e799 [Bluetooth] Add reset quirk for A-Link BlueUSB21 dongle
The new A-Link Bluetooth dongle is another one based on the BCM2046 chip
from Broadcom and it also needs to send HCI_Reset before it becomes fully
operational. Without the quirk it will show a lot of I/O errors.

Marcel Holtmann 4f62f6cb93 [Bluetooth] Add reset quirk for new Targus and Belkin dongles
Targus and Belkin have come out with new Bluetooth 2.1 capable dongles
using the latest BCM2046 chip from Broadcom. Both of them are so called
HID proxy dongles and they need to send HCI_Reset before they become
fully operational.

Marcel Holtmann 36010ff678 [Bluetooth] Fix double frees on error paths of btusb and bpa10x drivers
The transfer buffer of an URB will be automatically freed when using
the URB_FREE_BUFFER transfer_flag. So the extra calls to kfree() will
cause a double free.

Marcel Holtmann 5fbcd260c2 [Bluetooth] Fix USB disconnect handling of btusb driver
The USB transport specification for Bluetooth splits the ACL and SCO
handling into two separate interfaces. In Linux it possible to probe
and disconnect these interfaces independently. So make sure that both
interfaces are tightly bound together.

This fixes the suspend regression that some people have expierenced.

Marcel Holtmann e8c3c3d22b [Bluetooth] Fix wrong URB handling of btusb driver
The btusb driver contains two typos that result in some buggy behavior,
but the impact is not immediately visible.

During initialization the submitting of interrupt URBs might fail and
then make sure to remove the correct flag and not one of the hci_dev
flags.

When closing down the interface make sure to kill the anchor for the
ISOC URBs and not kill the interrupt URBs twice.

Also cancel any scheduled work when closing down the interface.

Marcel Holtmann bdbef3d696 [Bluetooth] Fix I/O errors on MacBooks with Broadcom chips
The newer MacBooks contain a Broadcom based Bluetooth chip and to make
this work properly, HCI_Reset must be send first. If HCI_Reset is not
used then a lot of I/O errors show up and its triggers packets from
non-existent ACL links.

Marcel Holtmann 9bfa35fe42 [Bluetooth] Add SCO support to btusb driver
The new generic driver for Bluetooth USB devices was missing proper
SCO support. The driver now claims the second interface for these USB
devices to allow the flow of SCO packets. It also handles switching
of the alternate setting and re-submission of isochronous URBs.

The btusb driver is now a full replacement for hci_usb and thus the
experimental tag has been removed and this driver is promoted as
preferred one.

Marcel Holtmann 5e23b923da [Bluetooth] Add generic driver for Bluetooth USB devices
This patch adds a new generic driver for Bluetooth USB devices. This
driver is still experimental at this point, but it is cleaner and
easier to maintain than the current Bluetooth USB driver. It is a
much better starting point for power management improvements.
