[PATCH] soc: dove: constify reset_control_ops structures

From: Bhumika Goyal
Date: Mon Jan 09 2017 - 11:35:14 EST


Declare reset_control_ops as const as they are only stored in the ops
field of a reset_controller_dev structure. This field is of type const
struct reset_control_ops *, so reset_control_ops structures having this
property can be declared as const.
Done using Coccinelle:
