[Qemu-devel] [PATCH v11 12/28] qapi: Factor out QAPISchemaObjectType.check_clash()

[Eric Blake]

Consolidate two common sequences of clash detection into a
new QAPISchemaObjectType.check_clash() helper method.

No change to generated code.

Signed-off-by: Eric Blake <address@hidden>

v11: don't lose isinstance check, and don't hide type.check()
inside check_clash()
v10: rebase on new Variants.check_clash()
v9: new patch, split off from v8 7/17
