Subject: [PATCH] [FIX] l10n_de: ensure o is defined in din5008 report
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

How to reproduce the bug:

- install l10n_de
- in Settings/General Settings/Business Documents, configure document
  layout to DIN 5008
- try to print one of several:
   => timesheet entries
   => direct debit mandates
   => follow-up reports

Bug:

When you use the DIN 5008 report defined in l10n_de, the o variable is
defined which generates an error.

closes odoo/odoo#81505
