Nvm, I don't think that this would give much benefit. @bors r+ |

As discussed in #3215, the
suspicious_trait_impllint causes too many false positives, as it is complex to find out if binary operations are suspicious or not.This PR restricts the number of binary operations to at most one, otherwise we don't lint.
This can be seen as very conservative, but at least FP can be reduced to bare minimum.
Fixes: #3215
changelog: limit the
suspicious_arithmetic_impllint to one binop, to avoid many FPs
