[PATCH] macintosh: windfarm_smu_sensors: constify wf_sensor_ops structures

[Bhumika Goyal]

Declare wf_sensor_ops structures as const as they are only stored in the
ops field of a wf_sensor structure. This field is of type const, so
wf_sensor_ops structures having this property can be made const too.
Done using Coccinelle:

@r disable optional_qualifier@
identifier x;
position p;
@@
static struct wf_sensor_ops x@p={...};

@ok@
struct smu_ad_sensor ads;
struct smu_cpu_power_sensor pow;
identifier r.x;
position p;
@@
(
ads.sens.ops=&x@p;
|
pow.sens.ops=&x@p;
)

@bad@
position p != {r.p,ok.p};
identifier r.x;
@@
x@p

@depends on !bad disable optional_qualifier@
identifier r.x;

+const
struct wf_sensor_ops x;
