+Subject: [PATCH] gvc-mixer-control: Really fix double-free when setting
+ headset
+
+In a28e23d9006a32c8982ad8bda11fec131c6b36e8, we said:
+The callbacks will be called repeatedly, once with data, and later
+on with eol == 0. Make sure to only free it when we get the eol call
+instead of once we've applied the settings.
+
+Whereas the docs say:
+When requesting all of these [instances] at once, the callback will be
+called multiple times, once for each object. When the list has been
+exhausted, the callback will be called without an information structure
+and the eol parameter set to a positive value.
+
+If an error occurs, the callback will be invoked without an information
+structure and eol set to a negative value.
+
+So, in all, we need to free our callback data when eol is positive, or
+negative. So, when it's not 0.
+
+Seems we got lucky in the original commit because the test machine only
+had a single soundcard.
