[PATCH v2 11/17] IB/mlx4: Delete an unnecessary variable initialisation in mlx4_ib_add()

Show all headers | View raw

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 21 Apr 2017 18:44:15 +0200

The local variable "new_counter_index" will be set to an appropriate pointer
a bit later. Thus omit the explicit initialisation at the beginning.
