Subject: Respond to Get Menu Language. bugzid: 547
X-Git-Tag: upstream/2.2.0~1^2~31^2~14
X-Git-Url: https://git.piment-noir.org/?p=deb_libcec.git;a=commitdiff_plain;h=fbdea54c9e414a98d3ff8ef4a4d03e7ff3568427

Respond to Get Menu Language. bugzid: 547

In the event that the menu language is undefined in libcec (currently
the default), the response will be a feature abort.
