Subject[PATCH 00/12] account for const type of of_device_id.data
Date
Maintain const annotations when putting values into the data field of
an of_device_id structure, and afterwards when extracting them from
the data field of such a structure.

This was done using the following semantic patch:
(http://coccinelle.lip6.fr/)

// <smpl>
@r@
identifier i,j;
const struct j *m;
struct i *y;
type T;
expression x,e;
position p;

(
y =@p (T)(of_device_get_match_data(...));
|
x = of_match_node(...);
... when != x = e
(
m = e;
|
y =@p (T)(x->data);
)
)
