Add a quirk to ignore Jabra speakerphone 410 and 510 devices HID
interface.
On those devices, the USB audio interface is working nicely,
but the HID interface is not working with the kernel usbhid driver,
and it requires a specific userspace program.
We could unbind it from userspace but just attaching the usbhid driver has
sometimes nasty effects:
either confusing the device state machine or triggering a storm of volume key
events making eventual sound UI blinking like crazy.

commit 6cd2c7db (videomode: videomode_from_timing work) changed the name of
the function from videomode_from_timing() to videomode_from_timings().

commit 32ed6ef1 (videomode: create enum for videomode's display flags) changed
the 'data_flags' field in videomode structure to 'flags'

Adapt to these changes in order to fix the following errors:

A race condition exists when registering the first watchdog device.
Sequence of events:

- watchdog_register_device calls watchdog_dev_register
- watchdog_dev_register creates the watchdog misc device by calling
  misc_register.
  At that time, the matching character device (/dev/watchdog0) does not yet
  exist, and old_wdd is not set either.
- Userspace gets an event and opens /dev/watchdog
- watchdog_open is called and sets wdd = old_wdd, which is still NULL,
  and tries to dereference it. This causes the kernel to panic.

Seen with systemd trying to open /dev/watchdog immediately after
it was created.

The driver and firmware sync up through SYNC messages, and the
firmware's affirmative reply to these SYNC messages appears to be the
"Reset" indication received via the status interrupt endpoint.  Thus the
driver needs the status interrupt endpoint always active so that the
Reset indication can be received even if the netdev is closed, which is
the case right after device insertion.

If the Reset indication is not received by the driver, it continues
sending SYNC messages to the firmware, which crashes about 10 seconds
later and the device stops responding.

Some drivers (sierra_net) need the status interrupt URB
active even when the device is closed, because they receive
custom indications from firmware.  Add functions to refcount
the status interrupt URB submit/kill operation so that
sub-drivers and the generic driver don't fight over whether
the status interrupt URB is active or not.

A sub-driver can call usbnet_status_start() at any time, but
the URB is only submitted the first time the function is
called.  Likewise, when the sub-driver is done with the URB,
it calls usbnet_status_stop() but the URB is only killed when
all users have stopped it.  The URB is still killed and
re-submitted for suspend/resume, as before, with the same
refcount it had at suspend.

Cancelling kiocbs requires adding them to a per kioctx linked list,
which is one of the few things we need to take the kioctx lock for in
the fast path.  But most kiocbs can't be cancelled - so if we just do
this lazily, we can avoid quite a bit of locking overhead.

While we're at it, instead of using a flag bit switch to using ki_cancel
itself to indicate that a kiocb has been cancelled/completed.  This lets
us get rid of ki_flags entirely.

This removes the only in-tree user of aio retry.  This will let us
remove the retry code from the aio core.

Removing retry is relatively easy as the USB gadget wasn't using it to
retry IOs at all.  It always fully submitted the IO in the context of
the initial io_submit() call.  It only used the AIO retry facility to
get the submitter's mm context for copying the result of a read back to
user space.  This is easy to implement with use_mm() and a work struct,
much like kvm does with async_pf_execute() for get_user_pages().

The support for PB1100, PB1500, and PB1550 got merged into the code for
DB1000 and DB1550 code in v3.7. When that was done the three related
Kconfig symbols were dropped. But not all related Kconfig macros were
removed. Do so now.

Note that the PB1100 code in the Au1100 LCD driver is removed entirely
and not converted to use its current Kconfig macro. That is done because
the macros it uses (PB1100_G_CONTROL, PB1100_G_CONTROL_BL, and
PB1100_G_CONTROL_VDD) are never defined. Actually only one of these was
ever defined (PB1100_G_CONTROL) but that define was removed in v2.6.34.
So, as far as I can tell, this code could have never compiled.
