24867	admin.E202 seems to include superclass references?	TorstenRottmann	nobody	"I have this three models defined:

{{{
class Act(models.Model):
    ....

class Form(Act):
    ...

class Diagnosis(Act):
    form = models.ForeignKey(Form)

}}}

...and this admin.py:
{{{
class DiagnosisInline(admin.TabularInline):
    model = Diagnosis
    ...

class FormAdmin(admin.ModelAdmin):
    ....
    inlines = [DiagnosisInline]

admin.site.register(Form, FormAdmin)
}}}

This triggers 'admin.E202':
{{{
<class 'nm.admin.DiagnosisInline'>: (admin.E202) 'nm.Diagnosis' has more than one ForeignKey to 'nm.Form'
}}}

Without looking into the source for this system check, I guess, that it counts all possible references, that lead to the admin class, the inline is included in.

And it counts two, from which one is right (Form) and one is wrong (Act), because it's already it's own superclass reference.

Am I right?
