Instead, make we enter usb/ directory on all

Some bluetooth dongles want ISO mode, and the limited support that the
sl811 offers today is sufficient. So add a Kconfig option for people
to optionally get access to the partial functionality.

This patch (as1455) removes the extra padding sent by g_file_storage
and g_mass_storage when the gadget wants to send less data than
requested by the host and isn't allowed to halt the bulk-IN endpoint.
Although the Bulk-Only Transport specification requires the padding to
be present, it isn't truly needed since the transfer will be terminated
by a short packet anyway. Furthermore, many existing devices don't
bother to send any padding.

Mass-storage and file-storage gadgets align the length to maximum-packet-size
when preparing the request to receive CBW. This is unnecessary and prevents the
controller driver from knowing that a short-packet is expected.
It is incorrect to set short_not_ok when preparing the request to receive CBW.
CBW will be a short-packet so short_not_ok must not be set.
This makes bh->bulk_out_intended_length unnecessary so it is also removed.

Prevent read urbs from being resubmitted from tasklet after port close.
The receive tasklet was not disabled on port close, which could lead to
corruption of receive lists on consecutive port open. In particular,
read urbs could be re-submitted before port open, added to free list in
open, and then added a second time to the free list in the completion
handler.

In the WDM class driver a disconnect event leads to calls to
usb_free_coherent to put back two USB DMA buffers allocated earlier.
The call to usb_free_coherent uses a different size parameter
(desc->wMaxCommand) than the corresponding call to usb_alloc_coherent
(desc->bMaxPacketSize0).
When a disconnect event occurs, this leads to 'bad dma' complaints
from usb core because the USB DMA buffer is being pushed back to the
'buffer-2048' pool from which it has not been allocated.
This patch against the most recent linux-2.6 kernel ensures that the
parameters used by usb_alloc_coherent & usb_free_coherent calls in
cdc-wdm.c match.

The modularization of the Blackfin driver set the name to "musb-blackfin"
in all the boards, but "musb-bfin" in the driver itself. Since the driver
file name uses "blackfin", change the driver to "musb-blackfin". This is
also easier as it's only one file to change.

This patch (as1453) fixes a long-standing bug in the ehci-hcd driver.
There is no need to set the Halt bit in the overlay region for an
unlinked or blocked QH. Contrary to what the comment says, setting
the Halt bit does not cause the QH to be patched later; that decision
(made in qh_refresh()) depends only on whether the QH is currently
pointing to a valid qTD. Likewise, setting the Halt bit does not
prevent completions from activating the QH while it is "stopped"; they
are prevented by the fact that qh_completions() temporarily changes
qh->qh_state to QH_STATE_COMPLETING.
On the other hand, there are circumstances in which the QH will be
reactivated _without_ being patched; this happens after an URB beyond
the head of the queue is unlinked. Setting the Halt bit will then
cause the hardware to see the QH with both the Active and Halt bits
set, an invalid combination that will prevent the queue from
advancing and may even crash some controllers.
Apparently the only reason this hasn't been reported before is that
unlinking URBs from the middle of a running queue is quite uncommon.
However Test 17, recently added to the usbtest driver, does exactly
this, and it confirms the presence of the bug.
In short, there is no reason to set the Halt bit for an unlinked or
blocked QH, and there is a very good reason not to set it. Therefore
the code that sets it is removed.

USB defines usb_device_type pointing to usb_device_pm_ops that
provides system-wide PM callbacks only and usb_bus_type pointing to
usb_bus_pm_ops that provides runtime PM callbacks only. However,
the USB runtime PM callbacks may be defined in usb_device_pm_ops
which makes it possible to drop usb_bus_pm_ops and will allow us
to consolidate the handling of subsystems by the PM core code.
