[PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacks 

In PM v1, all devices were called at SUSPEND_DISABLE level.  Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level.  However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.

Since this is obsolete infrastructure which is no longer necessary,
we can remove it.  Here's an (untested) patch to do exactly that.

int (*suspend) (struct device * dev, pm_message_t state, u32 level);
suspend is called to put the device in a low power state. There are
several stages to successfully suspending a device, which is denoted in
the @level parameter. Breaking the suspend transition into several
stages affords the platform flexibility in performing device power
management based on the requirements of the system and the
user-defined policy.
SUSPEND_NOTIFY notifies the device that a suspend transition is about
to happen. This happens on system power state transitions to verify
that all devices can successfully suspend.
A driver may choose to fail on this call, which should cause the
entire suspend transition to fail. A driver should fail only if it
knows that the device will not be able to be resumed properly when the
system wakes up again. It could also fail if it somehow determines it
is in the middle of an operation too important to stop.
SUSPEND_DISABLE tells the device to stop I/O transactions. When it
stops transactions, or what it should do with unfinished transactions
is a policy of the driver. After this call, the driver should not
accept any other I/O requests.
SUSPEND_SAVE_STATE tells the device to save the context of the
hardware. This includes any bus-specific hardware state and
device-specific hardware state. A pointer to this saved state can be
stored in the device's saved_state field.
SUSPEND_POWER_DOWN tells the driver to place the device in the low
power state requested.
Whether suspend is called with a given level is a policy of the
platform. Some levels may be omitted; drivers must not assume the
reception of any level. However, all levels must be called in the
order above; i.e. notification will always come before disabling;
disabling the device will come before suspending the device.
All calls are made with interrupts enabled, except for the
SUSPEND_POWER_DOWN level.
suspend is called to put the device in a low power state.
int (*resume) (struct device * dev, u32 level);
Resume is used to bring a device back from a low power state. Like the
suspend transition, it happens in several stages.
RESUME_POWER_ON tells the driver to set the power state to the state
before the suspend call (The device could have already been in a low
power state before the suspend call to put in a lower power state).
RESUME_RESTORE_STATE tells the driver to restore the state saved by
the SUSPEND_SAVE_STATE suspend call.
RESUME_ENABLE tells the driver to start accepting I/O transactions
again. Depending on driver policy, the device may already have pending
I/O requests.
RESUME_POWER_ON is called with interrupts disabled. The other resume
levels are called with interrupts enabled.
As with the various suspend stages, the driver must not assume that
any other resume calls have been or will be made. Each call should be
self-contained and not dependent on any external state.
Resume is used to bring a device back from a low power state.
