Marcel Holtmann b914a250e7 Bluetooth: Convert Marvell driver to use per adapter debugfs
The debugfs support of the Marvell driver is buggy. It is limited to one
controller per system. Fix this by using the controller specific debugfs
directory as parent.

Mike Frysinger 7427847d2d Bluetooth: Redo checks in IRQ handler for shared IRQ support
Commit ac019360fe changed the irq handler logic to BUG_ON rather than
returning IRQ_NONE when the incoming argument is invalid.  While this
works in most cases, it doesn't work when the IRQ is shared with other
devices (or when DEBUG_SHIRQ is enabled).

So revert the previous change and replace the warning message with a
comment explaining that we want this behavior.

Dominik Brodowski 5fa9167a1b pcmcia: rework the irq_req_t typedef
Most of the irq_req_t typedef'd struct can be re-worked quite
easily:

(1) IRQInfo2 was unused in any case, so drop it.

(2) IRQInfo1 was used write-only, so drop it.

(3) Instance (private data to be passed to the IRQ handler):
	Most PCMCIA drivers using pcmcia_request_irq() to actually
	register an IRQ handler set the "dev_id" to the same pointer
	as the "priv" pointer in struct pcmcia_device. Modify the two
	exceptions (ipwireless, ibmtr_cs) to also work this waym and
	set the IRQ handler's "dev_id" to p_dev->priv unconditionally.

(4) Handler is to be of type irq_handler_t.

(5) Handler != NULL already tells whether an IRQ handler is present.
	Therefore, we do not need the IRQ_HANDLER_PRESENT flag in
	irq_req_t.Attributes.

Linus Torvalds 404291ac9e btusb bluetooth driver: wait for 'waker' work too before closing
Rafael debugged a resume-time hang (with oopses in workqueue handling)
on his laptop that was due to the 'waker' workqueue entry being
disconnected and then released without the workqueue entry having been
synchronized.

Several people were involved, with Oleg Nesterov doing a debugging patch
showing what workqueue entry was corrupt etc.

This was a regression introduced by commit 7bee549e19 ("Bluetooth: Add
USB autosuspend support to btusb driver") as Rafael points out (not
actually bisected, but it became clear once the bug was found).

Oliver Neukum 7bee549e19 Bluetooth: Add USB autosuspend support to btusb driver
This patch adds support of USB autosuspend to the btusb driver.

If the device doesn't support remote wakeup, simple support based on
up/down is provided. If the device supports remote wakeup, additional
support for autosuspend while the interface is up is provided. This is
done by queueing URBs in an anchor structure and waking the device up
from a work queue on sending. Reception triggers remote wakeup.

The last busy facility of the USB autosuspend code is used. To close
a race between autosuspend and transmission, a counter of ongoing
transmissions is maintained.

Add #ifdefs for CONFIG_PM as necessary.

Wending Weng d2e353f7c3 Bluetooth: Fix false errors from bcsp_pkt_cull function
The error message "Removed only %u out of %u pkts" is printed when multiple
to be acked packets are queued.

    if (i++ >= pkts_to_be_removed)

This will break out of the loop and increase the counter i when
i==pkts_to_be_removed and the loop ends up with i=pkts_to_be_removed+1.

The following line

    if (i != pkts_to_be_removed) {
            BT_ERR("Removed only %u out of %u pkts", i, pkts_to_be_removed);
    }

Bluetooth shouldn't be doing this as most drivers don't support the flag,
furthermore it shouldn't be needed with newer buffering. This becomes rather

Alan Cox c65c9bc3ef tty: rewrite the ldisc locking
There are several pretty much unfixable races in the old ldisc code, especially
with respect to pty behaviour and also to hangup. It's easier to rewrite the
code than simply try and patch it up.

This patch
- splits the ldisc from the tty (so we will be able to refcount it more cleanly
  later)
- introduces a mutex lock for ldisc changing on an active device
- fixes the complete mess that hangup caused
- implements hopefully correct setldisc/close/hangup locking

There are still some problems around pty pairs that have always been there but
at least it is now possible to understand the code and fix further problems.

This fixes the following known bugs
- hang up can leak ldisc references
- hang up may not call open/close on ldisc in a matched way
- pty/tty pairs can deadlock during an ldisc change
- reading the ldisc proc files can cause every ldisc to be loaded

and probably a few other of the mysterious ldisc race reports.

I'm sure it also adds the odd new one.

Marcel Holtmann 43c2e57f94 Bluetooth: Submit bulk URBs along with interrupt URBs
Submitting the bulk URBs for ACL data transfers only on demand has no
real benefit compared to just submit them when a Bluetooth device gets
opened. So when submitting the interrupt URBs for HCI events, just
submit the bulk URBs, too.

This solves a problem with some Bluetooth USB dongles that has been
reported over the last few month. These devices require that the bulk
URBs are actually present. These devices are really broken, but there
is nothing we can do about it.

Marcel Holtmann 7a9d402053 Bluetooth: Send HCI Reset command by default on device initialization
The Bluetooth subsystem was not using the HCI Reset command when doing
device initialization. The Bluetooth 1.0b specification was ambiguous
on how the device firmware was suppose to handle it. Almost every device
was triggering a transport reset at the same time. In case of USB this
ended up in disconnects from the bus.

All modern Bluetooth dongles handle this perfectly fine and a lot of
them actually require that HCI Reset is sent. If not then they are
either stuck in their HID Proxy mode or their internal structures for
inquiry and paging are not correctly setup.

To handle old and new devices smoothly the Bluetooth subsystem contains
a quirk to force the HCI Reset on initialization. However maintaining
such a quirk becomes more and more complicated. This patch turns the
logic around and lets the old devices disable the HCI Reset command.

The only device where the HCI_QUIRK_NO_RESET is still needed are the
original Digianswer devices and dongles with an early CSR firmware.

CSR reported that they fixed this for version 12 firmware. The last
official release of version 11 firmware is build ID 115. The first
version 12 candidate was build ID 117.
