Hi Rafael,

I applied your patch-set against linux-next (next-20101124) with
backlight-type patches from Matthew.

# grep "error:" build_linux-next_next20101124.dileks.2.log
/home/sd/src/linux-2.6/linux-2.6.37-rc3/debian/build/source_i386_none/drivers/platform/x86/fujitsu-laptop.c:692:
error: implicit declaration of function ‘acpi_bus_get_power’

Looking into the source:

# grep acpi_bus_get_power -r
/home/sd/src/linux-2.6/linux-2.6.37-rc3/debian/build/source_i386_none/drivers/platform/x86/
/home/sd/src/linux-2.6/linux-2.6.37-rc3/debian/build/source_i386_none/drivers/platform/x86/fujitsu-laptop.c:
   result = acpi_bus_get_power(fujitsu->acpi_handle, &state);
/home/sd/src/linux-2.6/linux-2.6.37-rc3/debian/build/source_i386_none/drivers/platform/x86/fujitsu-laptop.c:
   result = acpi_bus_get_power(fujitsu_hotkey->acpi_handle, &state);

Checking the acpi tree:

# grep "acpi_bus_get_power(" -r
/home/sd/src/linux-2.6/linux-2.6.37-rc3/debian/build/source_i386_none/drivers/acpi/
/home/sd/src/linux-2.6/linux-2.6.37-rc3/debian/build/source_i386_none/drivers/acpi/bus.c:static
int __acpi_bus_get_power(struct acpi_device *device, int *state)
/home/sd/src/linux-2.6/linux-2.6.37-rc3/debian/build/source_i386_none/drivers/acpi/bus.c:
      result = __acpi_bus_get_power(device, &state);
/home/sd/src/linux-2.6/linux-2.6.37-rc3/debian/build/source_i386_none/drivers/acpi/bus.c:
      result = __acpi_bus_get_power(device, &state);

Just wanna let you know.

Kind Regards,

Hi,

Unfortunately there are a few problems with ACPI power resources management
that should be fixed by the following series of patches.

Patch [1/13] is necessary to fix a recent regression in the mainline kernel and
patch [2/13] also should go into 2.6.37 IMO.  The remaining patches are not so
urgent, but they all are necessary.

[1/13] - Fix regression if fan resume resulting from the rework of power
         resources reference counting.

[2/13] - Do not reference count power resources that can't be turned on.

[3/13] - Rework acpi_power_get_inferred_state() so that it doesn't update
         device->power.state behind the caller's back.

[4/13] - Introduce functions for handling lists of power resources.

[5/13] - Introduce helper function for reference counting power resources
         for a given device and power state.

[6/13] - Introduce function for reading device power state without modifying
         the device object.

[7/13] - Add function for device power state initialization.

[8/13] - Add function for updating device power state in a consistent way.

[9/13] - Register acpi_power_driver before scanning the root of the namespace.

[10/13] - Add power resource ACPI device objects as soon as they are needed.

[11/13] - Rework the management of ACPI power resources in the ACPI fan driver.

[12/13] - Drop acpi_bus_get_power() that has no users now.

[13/13] - Drop acpi_power_nocheck which isn't necessary any more.

The patches have been tested on my HP nx6325 (which is the only machine using
ACPI power resources I have) and a combo patch functionally equivalen to this
series has been tested by Maciej Rutecki.

Please apply.

Thanks,
Rafael
