Subject: en50221: fix menu text decoding
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=466a0143195a0a0f15c58d4bbd93c57b13caaccd;p=thirdparty%2Ftvheadend.git

en50221: fix menu text decoding

getmenutext() checks that dvb_get_string() returns greater than 0, but
that function returns 0 on success.

This causes menu text decoding to always fail, resulting in no menu
texts.

Fix the check to match dvb_get_string() behavior.
