Subject: ovsdb: Add default case to ovsdb_mutation_set_execute().
X-Git-Tag: v1.0.0~259^2~155
X-Git-Url: http://git.cascardo.eti.br/?a=commitdiff_plain;h=8b71367c38c9d2e57261fe7f30cbfc1d20b39401;p=cascardo%2Fovs.git

ovsdb: Add default case to ovsdb_mutation_set_execute().

The value of 'error' is indeterminate if m->mutator is not set to a valid
value here, so we should add a default case to handle the exception.  It
shouldn't happen, of course.
