All of these suppression prevent the detection of many common mistakes, and could easily prevent things like T231488. Especially if there are few issues of a given type, it's way better to suppress them inline, instead of disabling them for the whole core. This patch only touches the one with a lower count (although those counts may be out of date). Bug: T231636 Change-Id: Ica50297ec7c71a81ba2204f9763499da925067bd
