[PULL 18/20] acpi: Move maximum size logic into acpi_add_rom_blob() |
Date: |

From: David Hildenbrand <david@redhat.com>
We want to have safety margins for all tables based on the table type.
Let's move the maximum size logic into acpi_add_rom_blob() and make it
dependent on the table name, so we don't have to replicate for each and
every instance that creates such tables.
