This series is converting lists that contain the acpi_device_id
struct, which is defined in the include/linux/device-id/acpi.h
to makes 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 (as 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. 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
- actual implementations that make some of the modules use the new
driver_data_ptr
That way the task can be fragmented into manageable and independent
chunks of work and makes this effort easier to review.
Tested builds on arm64 and x86-64 in Yocto on 7.2-rc5
