46939f8b15 PCI PM: Put devices into low power states during late suspend (rev. 2)
Once we have allowed timer interrupts to be enabled during the late
phase of suspending devices, we are now able to use the generic
pci_set_power_state() to put PCI devices into low power states at
that time.  We can also use some related platform callbacks, like the
ones preparing devices for wake-up, during the late suspend.

Doing this will allow us to avoid the race condition where a device
using shared interrupts is put into a low power state with interrupts
enabled and then an interrupt (for another device) comes in and
confuses its driver.  At the same time, devices that don't support
the native PCI PM or that require some additional, platform-specific
operations to be carried out to put them into low power states will
be handled as appropriate.

f00a20ef46 PCI PM: Use pci_set_power_state during early resume
Once we have allowed timer interrupts to be enabled during the early
phase of resuming devices, we are now able to use the generic
pci_set_power_state() to put PCI devices into D0 at that time.  Then,
the platform-specific PM code will have a chance to handle devices
that don't implement the native PCI PM or that require some
additional, platform-specific operations to be carried out to power
them up.  Also, by doing this we can simplify the code quite a bit.

57ef80266e PCI PM: Consistently use variable name "error" for pm call return values
I noticed two functions use a variable "i" to store the return value of PM
function calls while the rest of the file uses "error". As "i" normally
indicates a counter of some sort it seems better to keep this consistent.

4aecd67189 PM: Change hibernation code ordering
Change the ordering of the hibernation core code so that the platform
"prepare" callbacks are executed and the nonboot CPUs are disabled
after calling device drivers' "late suspend" methods.

This change (along with the previous analogous change of the suspend
core code) will allow us to rework the PCI PM core so that the power
state of devices is changed in the "late" phase of suspend (and
analogously in the "early" phase of resume), which in turn will allow
us to avoid the race condition where a device using shared interrupts
is put into a low power state with interrupts enabled and then an
interrupt (for another device) comes in and confuses its driver.

2ed8d2b3a8 PM: Rework handling of interrupts during suspend-resume
Use the functions introduced in by the previous patch,
suspend_device_irqs(), resume_device_irqs() and check_wakeup_irqs(),
to rework the handling of interrupts during suspend (hibernation) and
resume.  Namely, interrupts will only be disabled on the CPU right
before suspending sysdevs, while device drivers will be prevented
from receiving interrupts, with the help of the new helper function,
before their "late" suspend callbacks run (and analogously during
resume).

In addition, since the device interrups are now disabled before the
CPU has turned all interrupts off and the CPU will ACK the interrupts
setting the IRQ_PENDING bit for them, check in sysdev_suspend() if
any wake-up interrupts are pending and abort suspend if that's the
case.

0a0c5168df PM: Introduce functions for suspending and resuming device interrupts
Introduce helper functions allowing us to prevent device drivers from
getting any interrupts (without disabling interrupts on the CPU)
during suspend (or hibernation) and to make them start to receive
interrupts again during the subsequent resume.  These functions make it
possible to keep timer interrupts enabled while the "late" suspend and
"early" resume callbacks provided by device drivers are being
executed.  In turn, this allows device drivers' "late" suspend and
"early" resume callbacks to sleep, execute ACPI callbacks etc.

The functions introduced here will be used to rework the handling of
interrupts during suspend (hibernation) and resume.  Namely,
interrupts will only be disabled on the CPU right before suspending
sysdevs, while device drivers will be prevented from receiving
interrupts, with the help of the new helper function, before their
"late" suspend callbacks run (and analogously during resume).

0d5a19f158 V4L/DVB (11297): cx23885: convert to v4l2_subdev.
Convert this driver to v4l2_subdev. Note that currently the only card with
analog support in this driver is the HVR-1800. The analog tuner support in
this driver is limited to what is needed for this board. When analog support
is added for other cards, then the tuner load code will probably have to be
expanded to take care of those boards. For example, there is currently no
support for either radio tuners or tda9887 demods.

I'd like to thank Steven Toth for testing this on his HVR-1800.

8bbd90ce80 V4L/DVB (11293): uvcvideo: Add zero fill for VIDIOC_ENUM_FMT
When enumerating formats with VIDIOC_ENUM_FMT the uvcvideo driver does not
fill the reserved fields of the struct v4l2_fmtdesc with zeros as required by
V4L2 API revision 0.24 [1]. Add the missing initializations.

The patch was tested with v4l-test 0.10 [2] with CNF7129 webcam found on EeePC
901.

7def728f55 V4L/DVB (11285): Remove unecessary udelay
When resetting the PID-filter block a safety msleep(1) was injected. Now that the function is called from interrupt context, it was replaced with a udelay. It seems that this delay is not necessary at all, let's remove it for now and test a while.

859f0277a6 V4L/DVB (11278): bttv: convert to v4l2_subdev since i2c autoprobing will disappear.
Since i2c autoprobing will disappear bttv needs to be converted to use
v4l2_subdev instead.

Without autoprobing the autoload module option has become obsolete. A warning
is generated if it is set, but it is otherwise ignored.

Since the bttv card definitions are of questionable value a new option was
introduced to allow the user to control which audio module is selected:
msp3400, tda7432 or tvaudio (or none at all).

By default bttv will use the card definitions and fallback on tvaudio as the
last resort.

If no audio device was found a warning is printed.

The saa6588 RDS device is now also explicitly probed since it is no longer
possible to autoprobe it. A new saa6588 module option was added to override
the card definition since I suspect more cards have this device than one
would guess from the card definitions.

Note that the probe addresses of the i2c modules are hardcoded in this
driver. Once all v4l drivers are converted to v4l2_subdev this will be
cleaned up. Such data belongs in an i2c driver header.
