devtmpfs: missing initialialization in never-hit case
create_path() on something without a single / in it will return err without initializing it. It actually can't happen (we call that thing only if create on the same path returns -ENOENT, which won't happen happen for single-component path), but in this case initializing err to 0 is more than making compiler to STFU - would be the right thing to return on such paths; the function creates a parent directory of given pathname and in that case it has no work to do...
