You will probably need to remove HCI_QUIRK_BROKEN_ERR_DATA_REPORTING
last otherwise it breaks the build in between patches, and please
double check if there are no other instances of driver using it or
perhaps leave it defined in case the feature is broken for some reason
but then we need a macro that checks both the quirk and the feature
bit.
