<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang-tools-extra Author: Julian Schmidt (5chmidti) <details> <summary>Changes</summary> Previously, the call to `findArgs` for a `CallExpr` inside of a `min` or `max` call would call `findArgs` before checking if the argument is a call to `min` or `max`, which is what `findArgs` is expecting. The fix moves the name checking before the call to `findArgs`, such that only a `min` or `max` function call is used as an argument.
