[PATCH] ARM: prima2: constify reset_control_ops structures

[PATCH] ARM: prima2: constify reset_control_ops structures

[Bhumika Goyal]

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:

identifier i;

static struct reset_control_ops i@p={...};

@ok1@
identifier r1.i;
position p;
struct reset_controller_dev x;

x.ops=&i@p;

@bad@
position p!={r1.p,ok1.p};
identifier r1.i;

i@p

@depends on !bad disable optional_qualifier@
