This series contains cleanups to remove unneeded variable, header file, function forward declaration and so on. More details can be found in the respective changelogs. This patch (of 4): The local variable ret is always equal to -ENOMEM and never touched. So remove it and return -ENOMEM directly to simplify the code.
