This is the result after running ACPICA release automation tool from the following point:
https://github.com/acpica/acpica/commit/e714615f
The command to confirm the result is:
# generate/linux/gen-repo e714615f
The spaces added by this patch are fixed by this ACPICA commit:
https://github.com/acpica/acpica/commit/b2294cae
This commit is released in this ACPICA release cycle as [PATCH 02].
So what have been made wrong here will be made correct by PATCH 02.

ACPICA release scripts have already been aware of u8 as a type, so the indentation is not wrong after running ACPICA release scripts.
While acpi_size is not, acpi_size is fixed by the above mentioned commit:
https://github.com/acpica/acpica/commit/b2294cae
This commit is released in this ACPICA release cycle as [PATCH 02].
So what haven't been fixed here will be fixed by [PATCH 02].

As u8, ACPICA release scripts have been aware of acpi_opearnd_object as a type.
As acpi_gpe_block_info, ACPICA release scripts wasn't aware of acpi_walk_state as a type.

The only way to make it looking correct is to merge PATCH 01 into PATCH 02.
But I need to make sure that I won't have to make this release cycle more than twice...
Otherwise I need to keep them separated in order to reduce human interventions.
