Hi,
I wonder why acpi doesn't use request_region/request_mem_region on the resource
used by the interpreter.
For example ioport resource are declared in dsdt with OperationRegion.
A good place to do that could be acpi_os_validate_address.
I believe by doing that acpi will avoid that other drivers try to use the same r
esource. And it will avoid the acpi_check_region hack that need to be added in e
ach driver instead of relying with the standard
request_region/request_mem_region mecanism.
