Subject[PATCH] reset: constify reset_control_ops structures
Date
Declare reset_control_ops structures 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:
