Staging: speakup: varhandlers: cleanup of function spk_get_punc_var
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 Signed-off-by: Saurabh Sengar <saurabh.truth@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
