This patch set adds generic abstract layer support for acpi video driver to
have generic user interface to control backlight and output switch control by
leveraging the existing backlight sysfs class driver, and by adding a new
video output sysfs class driver.
This patch:
Add dev argument for backlight_device_register to link the class device to
real device object. The platform specific driver should find a way to get the
real device object for their video device.

Thanks to several earlier patches, usb_autosuspend_device() and
usb_autoresume_device() are never called with a second argument other
than 1. This patch (as819) removes the now-redundant argument.
It also consolidates some common code between those two routines,
putting it into a new subroutine called usb_autopm_do_device(). And
it includes a sizable kerneldoc update for the affected functions.

This patch (as818b) simplifies autosuspend processing by keeping track
of the number of unsuspended children of each USB hub. This will
permit us to avoid a good deal of unnecessary work all the time; we
will no longer have to create a bunch of workqueue entries to carry
out autosuspend requests, only to have them fail because one of the
hub's children isn't suspended.
The basic idea is simple. There already is a usage counter in the
usb_device structure for preventing autosuspends. The patch just
increments that counter for every unsuspended child. There's only one
tricky part: When a device disconnects we need to remember whether it
was suspended at the time (leave the counter alone) or not (decrement
the counter).

This patch (as817) simplifies the remote-wakeup processing in the hub
driver. Now instead of using a specialized code path, it relies on
the standard USB resume routines. The hub_port_resume() function does
an initial get_port_status() to see whether the port has already
resumed itself (as it does when a remote-wakeup request is sent).
This will slow down handling of other resume events slightly, but not
enough to matter.
The patch also changes the hub_port_status() routine, making it return
an error if a short reply is received.

Unlike UHCI, OHCI does not exert any DMA load on the system when no
devices are connected. Consequently there is no advantage to doing
an autostop other than the power savings, so we shouldn't compile the
necessary code unless CONFIG_PM is enabled.
This patch (as820) makes the root-hub suspend and resume routines
conditional on CONFIG_PM. It also prevents autostop from activating
if the device_may_wakeup flag isn't set; some people use this flag to
alert the driver about Resume-Detect bugs in the hardware.

This patch (as742b) adds autosuspend/autoresume support to the USB hub

This patch (as738b) fixes numerous problems in the controller/root-hub
suspend/resume/remote-wakeup support in ehci-hcd:
The bus_resume() routine should wake up only the ports that
were suspended by bus_suspend(). Ports that were already
suspended should remain that way.
The interrupt mask is used to detect loss of power in the
bus_resume() routine (if the mask is 0 then power was lost).
However bus_suspend() always sets the mask to 0. Instead the
mask should retain its normal value, with port-change-detect
interrupts disabled if remote wakeup is turned off.
The interrupt mask should be reset to its correct value at the
end of bus_resume() regardless of whether power was lost.
bus_resume() reinitializes the operational registers if power
was lost. However those registers are not in the aux power
well, hence they can lose their values whenever the controller
is put into D3. They should always be reinitialized.
When a port-change interrupt occurs and the root hub is
suspended, the interrupt handler should request a root-hub
resume instead of starting up the controller all by itself.
There's no need for the interrupt handler to request a
root-hub resume every time a suspended port sends a
remote-wakeup request.
The pci_resume() method doesn't need to check for connected
ports when deciding whether or not to reset the controller.
It can make that decision based on whether Vaux power was
maintained.
Even when the controller does not need to be reset,
pci_resume() must undo the effect of pci_suspend() by
re-enabling the interrupt mask.
If power was lost, pci_resume() must not call ehci_run().
At this point the root hub is still supposed to be suspended,
not running. It's enough to rewrite the command register and
set the configured_flag.

Certain boards seem to like to issue false overcurrent notifications, for
example on ports that don't have anything connected to them. This looks
like a hardware error, at the level of noise to those ports' overcurrent
input signals (or non-debounced VBUS comparators). This surfaces to users
as truly massive amounts of syslog spam from khubd (which is appropriate
for real hardware problems, except for the volume from multiple ports).
Using this new "ignore_oc" flag helps such systems work more sanely, by
preventing such indications from getting to khubd (and spam syslog). The
downside is of course that true overcurrent errors will be masked; they'll
appear as spontaneous disconnects, without the diagnostics that will let
users troubleshoot issues like short circuited cables.
Note that the bulk of these reports seem to be with VIA southbridges, but
I think some were with Intel ones.

Hi everyone,
Sorry for the long time response but here is the patch, I think this way should
work, if anyone has any suggestion let me know. What I do now is, in case I
don't have the tty available I reschedule the work, I have tried it and it
works with no problem, I even tried removing the device, and didn't find
anything strange.

All the other root-hub suspend or resume log messages, in ohci-hcd or
any of the other host controller drivers, use the debug priority
level. This patch (as815) makes the one single exception behave like
all the rest.

Several functions in USB core overlap with global functions.
The linker appears to do the right thing, but it is bad practice and makes
debugging harder.

This patch (as809b) moves the declaration of the hub driver's private
data structure from hub.h into the hub.c source file. Lots of other
files import hub.h; they have no need to know about the details of the
hub driver's private data.

This patch (as814) adds usb_autopm_set_interface() to the autosuspend
API. It also provides convenient wrapper routines,
usb_autopm_enable() and usb_autopm_disable(), for drivers that want
to specify directly whether autosuspend should be allowed.

This patch (as813) gathers together common code for USB interface
autosuspend/autoresume.
It also adds some simple checking at the time an autosuspend request
is made, to see whether the request will fail. This way we don't
add a workqueue entry when it would end up doing nothing.

We have no benefits of having the usb_endpoint_* functions as functions,
but making them inline saves text and data segment sizes:
text data bss dec hex filename
14893634 3108770 1108840 19111244 1239d4c vmlinux.func
14893185 3108566 1108840 19110591 1239abf vmlinux.inline
This is the result of a 2.6.19-rc3 kernel compiled with GCC 4.1.1 without
CONFIG_MODULES, CONFIG_CC_OPTIMIZE_FOR_SIZE, CONFIG_REGPARM options set.
USB support is fully enabled (while most of the other drivers are not),
and that kernel has most of the USB code ported to use the endpoint
functions.
That happens because a call to those functions are expensive (in terms
of bytes), while the function's size is smaller or have the same 'size' of
the call.
