USB: serial: sierra: put reset_resume callback back.

A few patches ago, I removed the reset_resume callback in this driver.
Now that the usb-serial core supports reset_resume, put this driver
callback back as well, so it should work identically to how it was
originally.

Now if this function really is doing what it should be doing, well,
that's a different story, but we are at least doing the identical thing
that we were before...

USB: EHCI: improve full-speed isochronous scheduling routine

This patch (as1555) improves the code ehci-hcd uses while checking the
periodic schedule for isochronous transfers to full-speed devices.  In
addition to making sure that a new transfer does not violate the
restrictions on the high-speed schedule, it also has to check the
restrictions on the full-speed part of the bus, i.e., the part beyond
the Transaction Translator (TT).

It does this by calling tt_available() (or tt_no_collision() if
CONFIG_USB_EHCI_TT_NEWSCHED isn't enabled).  However it calls that
routine on each pass through a loop over the frames being modified,
which is an unnecessary expense because tt_available() (or
tt_no_collision) already does its own loop over frames.  It is
sufficient to do the check just once, before starting the loop.

In addition, the function calls incorrectly converted the transfer's
period from microframes to frames by doing a left shift instead of a
right shift.  The patch fixes this while moving the calls.

USB: gpio_vbus: avoid consecutive vbus_session calls with the same "is_active"

Basically, ->vbus_session() calls should be served when VBUS session
starts and ends (it's not whenever transciever drivers detect VBUS
_changes_).  Otherwise, if UDC gadget drivers don't want for some
reason ->vbus_session() calls with the same "is_active" value, either
OTG or UDC drivers need to have some protection handlings.

Also, on platforms using this 'gpio_vbus' driver, the driver is only
allowed to check whether VBUS is applied.  There is no kernel-standard
way prepared for UDC gadget drivers to do that.

With this in mind, gpio_vbus should try to prevent unnecessary
consecutive vbus_session calls being served with the same "in_active"
value.

USB: cdc-wdm: remove from device list on disconnect

Prevents dereferencing an invalid struct usb_interface
pointer.

Always delete entry from device list whether or not the
rest of the device state cleanup is postponed. The device
list uses desc->intf as key, and wdm_open will dereference
this key while searching for a matching device.  A device
should not appear in the list unless probe() has succeeded
and disconnect() has not finished.

usb: gadget: ci13xxx: rename register layouts

Currently, the register prefixes in the driver seem to be mixed: the
capability registers are the ones that contain capability information,
such as number of hardware endpoints, while the registers that are
used to program the controller are called operational registers.

Normally, capability registers start at 0x100 offset of the register
window and are followed by operational registers. In some versions,
however, capability registers start at 0x0 offset.

This patch renames the register and adjusts their offsets appropriately,
leaving the possibility of having a non-standard capability offset.

I couldn't find any mentions of the TESTMODE register anywhere, so I
suspect it might only be enabled in chipidea internal versions of the
controller and I'm really inclined to remove it from the driver or at
least hiding it behind a config option.

usb: gadget: ci13xxx: fix ep list removal in gadget unregistering code

Since ep0{out,in} are never on gadget's ep_list, there's no need to try
to unlink them, even more so because ep_list linkage is not initialized
for these endpoints.

ohci-da8xx: set MODULE_ALIAS to allow autoloading

The Davinci USB platform device (in mach-davinci/usb.c) uses "ohci"
as the name. To allow autoloading of the relevant driver, the module
needs to set the MODULE_ALIAS.

USB: make vendor id of root hubs greppable

It took me surprisingly long to find the location where the Linux
Foundation vendor id (0x1d6b) is set for the root hubs. A minor update
to three comments makes those locations (trivially) greppable.

USB: ffs-test: fix length argument of out function call

The out functions should only handle actual available data instead of the complete buffer.
Otherwise for example the ep0_consume function will report ghost events since it tries to decode
the complete buffer - which may contain partly invalid data.

USB: xhci-hcd: print URB's expected length in decimal, not hex

This patch changes the output format specifier of a debugging line in
the xhci-hcd driver.  An URB's transfer_buffer_length should be
printed in decimal; there's no reason to print it in hex.  Especially
since the actual_length value, printed earlier on the same line, is
already in decimal.

I can't remember why I wrote it like this many many years ago, but it's
not needed at all, let's rely on the usb-serial core for this function,

usb-serial: clean up unneeded PM-related fields

This patch (as1551) cleans up the PM-related entries in the usb_driver
structures of the various USB serial driver modules.  Those entries
are now filled in by the usb-serial core during driver registration,
so they don't need to be initialized explicitly in the source code.

The same is true of the one remaining no_dynamic_id entry.

reset_resume remains a small problem, because the serial core doesn't
support it.  The patch ignores these entries.
