The functionality of acpi_dev_irqresource_disabled() is same as in common irqresource_disabled(), so drop acpi_dev_irqresource_disabled() in favour of that function.

This reverts commit 8a66790b7850a6669129af078768a1d42076a0ef. Switching this function to AE_CTRL_TERMINATE broke the documented behaviour of acpi_dev_get_resources() - AE_CTRL_TERMINATE does not, in fact, terminate the resource walk because acpi_walk_resource_buffer() ignores it (specifically converting it to AE_OK), referring to that value as "an OK termination by the user function". This means that acpi_dev_get_resources() does not abort processing when the preproc function returns a negative value.

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

As said in commit f2c2cbcc35d4 ("powerpc: Use pr_warn instead of
pr_warning"), removing pr_warning so all logging messages use a
consistent <prefix>_warn style. Let's do it.

Some devices have limited addressing capabilities and cannot reference the whole memory address space while carrying out DMA operations (eg some devices with bus address bits range smaller than system bus - which prevents them from using bus addresses that are otherwise valid for the system). The ACPI _DMA object allows bus devices to define the DMA window that is actually addressable by devices that sit upstream the bus, therefore providing a means to parse and initialize the devices DMA masks and addressable DMA range size. By relying on the generic ACPI kernel layer to retrieve and parse resources, introduce ACPI core code to parse the _DMA object.

The function acpi_dev_get_resources() is completely generic and can be used to parse resource objects that are not necessarily coming from the _CRS method but also from other objects eg _DMA that have the same _CRS resource format. Create an acpi_dev_get_resources() helper, internal to the ACPI resources parsing compilation unit, __acpi_dev_get_resources(), that takes a const char* parameter to detect which ACPI method should be called to retrieve the resources list and make acpi_dev_get_resources() call it with a method name _CRS leaving the API behaviour unchanged.
