Fix table mismatch shown in schema module

I have schema module installed and reports a mis match, is this ok to continue?
column revision_id - differences on: not null, default
declared: array('description' => 'TODO: please describe this field!', 'type' => 'int', 'unsigned' => TRUE, 'not null' => FALSE)
actual: array('description' => 'The entity revision ID this term is attached to.', 'type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'default' => 0)
