[PATCH v2 0/4] dma: use designated initializers for acpi_device_id

[Pawel Zalewski]

This series is converting lists that contain the acpi_device_id struct,
which is defined in the include/linux/device-id/acpi.h to make use of named
initializers (which they do not use currently). This work is part of the on
going effort in the kernel associated with device-ids [1]

The plan is to convert acpi_device_id::driver_data to have an anonymous
union, similarly to what was introduced for PCI and I2C device ID tables.
The goal is to increase type-safety (most of the existing casts are gone),
to improve readability and to make use intent a bit more clear:

```
union {
	kernel_ulong_t driver_data;
	const void *driver_data_ptr;
}
```

But for that to work all lists containing the structs need to use named
initializers first to avoid triggering -Wmissing-braces. I already have
patches that implement this and touching a lot of kernel subsystmes that
use the acpi_device_id struct and that list keeps on growing. Therefore, 
I have decided to split the series per every subsystem into:
- pre-clean-ups that convert the lists to use named initializers
  (which is this series)
- actual implementations that make some of the modules use the new 
  driver_data_ptr member

That way the task can be fragmented into manageable and independent chunks
of work and makes this effort easier to review.

Tested builds on x86-64 and a64 in Yocto using 7.3-rc2.
