The idea is that test suites such as IGT use this information to check that frames that are exected to be identical, also have identical CRC values. Other drivers for hardware that can provide frame CRCs (including eDP panels that support self-refresh) can easily implement the new callback and provide userspace with the CRC values. Sorry about that, but there was a dangling brace in v10 breaking the build so here is this v11.
