+Subject: [PATCH] sensors: Correctly handle the return value of
+ QCollator::compare
+
+QCollator::compare() can return any integer, not just [-1, 0, 1].
+Comparing the result with -1 happened to work with most locales,
+but it broke with the C locale. As a result, when sensors were put
+into std::map, they were sometimes erroneously treated as duplicates,
+leading to a randomly incomplete and garbled sensor list.
