You should be able to just run `clang-format` over your edited code and that should reformat it to make the format checker happy.
There are some function calls (`close()` for example) between testing the `errno` value and printing out the log line. These functions might reset `errno` to something else. You should either reorder the code so that the log printing happens immediately after testing `errno`, or save the value to an intermediary variable and then print that.
