    Subject[PATCH 04/10] md/dm-crypt: Delete an unnecessary variable initialisation in crypt_message()
    From
    Date
    From: Markus Elfring <elfring@users.sourceforge.net>
    Date: Wed, 28 Sep 2016 15:06:05 +0200

    The local variable "ret" will be set to an appropriate value in if branches.
    Thus omit the explicit initialisation at the beginning.
