[Qemu-devel] [PULL v2 36/47] hmp: Use qapi_enum_parse() in hmp_migrate_set_capability()

[Markus Armbruster]

From: Marc-André Lureau <address@hidden>

The error message on invalid capability name changes from

    Invalid parameter "NAME"

to

    invalid parameter value: NAME

No worse than before.
