Based on my knowledge of Django's inspectdb command, I can create the patch. The inspectdb command is located in `django/core/management/commands/inspectdb.py`. The issue is that when multiple ForeignKey fields in a model point to the same related model, Django raises E304 error about clashing reverse accessors.

The fix needs to:
1. Track which related models have been used for foreign key relationships in each table
2. When a related model is used more than once, add `related_name` to all ForeignKey fields pointing to that model to avoid the reverse accessor clash

Here is the patch for Django's inspectdb command:

Wait, let me reconsider the Django inspectdb structure more carefully. Based on my knowledge, the code structure is different. Let me provide a more accurate patch:
