help with fixing code for 2.6.29-rc7

[Norbert Preining]

Hi everyone,

I am trying to fix some code for 2.6.29-rc7:

... acpi_handle handle ...

        struct acpi_namespace_node *node;
        union acpi_operand_object *operand;

1       node = (struct acpi_namespace_node *)handle;
2       operand = (union acpi_operand_object *)node->object;

3       printk(KERN_WARNING DRV_PFX "method: name: %4.4s, args %X\n", node->name.ascii,
4              (u32) operand->method.param_count);

Compiling that I get errors
	error: dereferencing pointer to incomplete type
in line 2,3,4.

Any suggestion how to fix that?

Thanks a lot

Norbert

Seemingly, struct acpi_namespace_node is undefined.

Thanks,

Thanks, good point. The problem is that they are used in the sony-laptop
module for Sony-Z series laptops. I copied the relevant three acpica/*.h
files to the build directory and added includes, now it compiles and
works fine.

Best wishes

Norbert
