`golint` had the following issue when linting this file: ``` daemon/logger/jsonfilelog/read.go:116:10: should omit type io.Reader from declaration of var rdr; it will be inferred from the right-hand side ``` In order to keep it happy changing it to an indirect assignment will still maintain the same functionality.
