This patch does the following:
* changed the complicated if statements to simple case statements
* in case of E_DEFAULT, no need to return error as ERESTART,
because this is the user asked for. Hence function should return success.
* ret variable is 0 always, hence removed it.
* removed one ternary operator, as it was always returning the status value only,
and hence removed the status variable too
