This patch (as1344) removes references to port->port.count from the
USB serial drivers.  Now that serial ports are properly reference
counted, port.count checking is unnecessary and incorrect.  Drivers
should assume that the port is in use from the time the open method
runs until the close method is called.

While looping over the interfaces, if usb_hcd_alloc_bandwidth() fails it calls
hcd->driver->reset_bandwidth(), so there was no need to reinstate the interface
again.

If no break occurred, the index equals config->desc.bNumInterfaces. A
subsequent usb_control_msg() failure resulted in a read from
config->interface[config->desc.bNumInterfaces] at label reset_old_alts.

In either case the last interface should be skipped.

This patch (as1347) makes some adjustments to the way usb-storage
handles the request-queue parameters.

USB host controllers are able to handle arbitrarily long
scatter-gather lists, since they are limited only by main memory and
not by the controller hardware.  Hence the sg_tablesize field in the
host template can be increased to the maximum value.

Drivers like usb-storage aren't supposed to touch the queue's
max_sectors parameter; instead they are supposed to use the
max_hw_sectors value.  Accordingly, the patch replaces calls of
queue_max_sectors() with calls of queue_max_hw_sectors().  Oddly
enough, the blk_queue_max_sectors() routine is nevertheless still
appropriate.

The existing code imposes a limit of SCSI_DEFAULT_MAX_SECTORS (1024)
on the values accepted by the max_sectors attribute file.  There's no
reason not to accept larger values, so the limit is removed.  (It
would be nice to change the file's name to max_hw_sectors, but the old
name is already a well-established API.)

Texas Instruments DA8xx/OMAP-L1x OHCI glue layer.

This OHCI implementation is not without quirks: there's only one physical port
despite the root hub reporting two; the port's power control and over-current
status bits are not connected to any pins, however, at least on the DA830 EVM
board, those signals are connected via GPIO, thus the provision was made for
overriding the OHCI port power and over-current bits at the board level...

A crash has been reported with sierra driver on disconnect with
Ubuntu/Lucid distribution based on kernel-2.6.32.
The cause of the crash was determined as "NULL tty pointer was being
referenced" and the NULL pointer was passed by sierra_indat_callback().

This patch modifies sierra_indat_callback() function to check for NULL
tty structure pointer. This modification prevents a crash from happening
when the device is disconnected.

This patch addresses two problems:

1) Bulk reads should always use the DATA0 for the pid, and the write
   PID should toggle between DATA0 and DATA1.  The fix is using
   dbgp_pid_write_update() and dbgp_pid_read_update().

2) The delay loop for waiting for a transaction was not long enough to
   always complete the initial handshake inside dbgp_wait_until_done().
   After the initial handshake the maximum delay length is never reached.

The combined result of these two changes allows for the removal of the
forced resynchronization where a bulk write was issued with a dummy
data payload only to get the device to start accepting data writes
again.

When the HDC driver writes the data to the transfer buffers it pollutes
the D-cache (unlike DMA drivers where the device writes the data). If
the corresponding pages get mapped into user space, there are no
additional cache flushing operations performed and this causes random
user space faults on architectures with separate I and D caches
(Harvard) or those with aliasing D-cache.

Adds a fallback which forces all LUNs ejection (including
non-removable and with prevent_medium_removal flag) when mass storage
function (MSF) worker thread exits and gadget fails to handle the
situation.

Previously, if thread_exits was not specified mass storage function
(MSF) did nothing when exiting thread as it's unclear for *function*
what to do when it's thread terminates so responsibility of handling
this situation was left to the *gadget* using the function.

The g_mass_storage handled the situation by unregistering itself (the
same thing that file storage gadget does).  However, g_multi did
nothing and so MSF did not eject LUNs which prevented file system
unmounting.
