When calling debugfs functions, there is no need to ever check the

never do something different based on this.

The variable temp is incorrectly being updated, instead it should

and loops forever. Thanks to Alan Stern for pointing out the

Now that the SPDX tag is in all USB files, that identifies the license
in a specific and legally-defined manner. So the extra GPL text wording
can be removed as it is no longer needed at all.
This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text. And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.
No copyright headers or other non-license-description text was removed.

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.
Update the drivers/usb/ and include/linux/usb* files with the correct
SPDX license identifier based on the license text in the file itself.
The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.
This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

The debugging facilities in ehci-dbg.c follow an uneven pattern. Some
of them are protected by "#ifdef CONFIG_DYNAMIC_DEBUG" and some
aren't, presumably in the hope of having some of the debugging output
available in any configuration.
This leads to build problems when dynamic debugging isn't configured.
Rather than try to keep this complicated state of affairs, let's just
make everything dependent on CONFIG_DYNAMIC_DEBUG.

This patch continues the scheduling changes in ehci-hcd by adding a
table to store the bandwidth allocation below each TT. This will
speed up the scheduling code, as it will no longer need to read
through the entire schedule to compute the bandwidth currently in use.
Properly speaking, the FS/LS budget calculations should be done in
terms of full-speed bytes per microframe, as described in the USB-2
spec. However the driver currently uses microseconds per microframe,
and the scheduling code isn't robust enough at this point to change
over. For the time being, we leave the calculations as they are.

This patch significantly changes the scheduling code in ehci-hcd.
Instead of calculating the current bandwidth utilization by trudging
through the schedule and adding up the times used by the existing
transfers, we will now maintain a table holding the time used for each
of 64 microframes. This will drastically speed up the bandwidth
computations.
In addition, it eliminates a theoretical bug. An isochronous endpoint
may have bandwidth reserved even at times when it has no transfers
listed in the schedule. The table will keep track of the reserved
bandwidth, whereas adding up entries in the schedule would miss it.
As a corollary, we can keep bandwidth reserved for endpoints even
when they aren't in active use. Eventually the bandwidth will be
reserved when a new alternate setting is installed; for now the
endpoint's reservation takes place when its first URB is submitted.
A drawback of this approach is that transfers with an interval larger
than 64 microframes will have to be charged for bandwidth as though
the interval was 64. In practice this shouldn't matter much;
transfers with longer intervals tend to be rather short anyway (things
like hubs or HID devices).
Another minor drawback is that we will keep track of two different
period and phase values: the actual ones and the ones used for
bandwidth allocation (which are limited to 64). This adds only a
small amount of overhead: 3 bytes for each endpoint.
The patch also adds a new debugfs file named "bandwidth" to display
the information stored in the new table.

This patch begins the process of unifying the scheduling parameters
that ehci-hcd uses for interrupt and isochronous transfers. It
creates an ehci_per_sched structure, which will be stored in both
ehci_qh and ehci_iso_stream structures, and will contain the common
scheduling information needed for both.
Initially we merely create the new structure and move some existing
fields into it. Later patches will add more fields and utilize these
structures in improved scheduling algorithms.

This patch (as1664) converts ehci-hcd's async_unlink, async_iaa, and
intr_unlink from singly-linked lists to standard doubly-linked
list_heads. Originally it didn't seem necessary to use list_heads,
because items are always added to and removed from these lists in FIFO
order. But now with more list processing going on, it's easier to use
the standard routines than continue with a roll-your-own approach.
I don't know if the code ends up being notably shorter, but the
patterns will be more familiar to any kernel hacker.

This patch (as1622) removes the USB-2.1 Link Power Management code
from the ehci-hcd driver. This code was never integrated with
usbcore, it is full of bugs, and it was not getting used by anybody.
However, the debugging code for dumping the LPM-related fields in the
EHCI registers is left in place. In theory it might be useful to see
these values, even though we don't use them.
This essentially amounts to a partial revert of commit
aa4d8342988d0c1a79ff19b2ede1e81dfbb16ea5 (USB: EHCI: EHCI 1.1
addendum: preparation) and an almost full revert of commit

EHCI_RH_STOPPING. This value is used at times when the root hub is

finished all its DMA yet.
Although the purpose may not be apparent, this distinction will come
in useful later on. Future patches will avoid actions that depend on
the root hub being operational (like turning on the async or periodic
schedules) when they see the state is EHCI_RH_STOPPING.

This patch (as1489) works around a hardware bug in MosChip EHCI
controllers. Evidently when one of these controllers increments the
frame-index register, it changes the three low-order bits (the
microframe counter) before changing the higher order bits (the frame
counter). If the register is read at just the wrong time, the value
obtained is too low by 8.
When the appropriate quirk flag is set, we work around this problem by
reading the frame-index register a second time if the first value's
three low-order bits are all 0. This gives the hardware a chance to
finish updating the register, yielding the correct value.

This patch (as1483) improves the ehci-hcd driver family by getting rid
of the reliance on the hcd->state variable. It has no clear owner and
it isn't protected by the usual HCD locks. In its place, the patch

Along the way, the patch removes a couple of lines containing

state simply gets changed to the RUNNING state, because the driver
doesn't make any distinction between them.

With pre-release GCC-4.6, there are several complaints of variables
that are 'set but not used' caused by the ehci_vdbg() macro expanding

this warning by rewriting ehci_vdbg() as a variadic static inline that
