Drop call to of_match_device, which is subsumed by the subsequent
call to of_device_get_match_data. The code becomes simpler, and a
temporary variable can be dropped.
The semantic match that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@r@
local idexpression match;
identifier i;
expression x, dev, e, e1;
@@
- match@i = of_match_device(x, dev);
- if (match) e = of_device_get_match_data(dev);
- else e = e1;
+ e = of_device_get_match_data(dev);
+ if (!e) e = e1;
@@
identifier r.i;
@@
- const struct of_device_id *i;
... when != i

The equivalent of this is now done via macro magic when
the relevant register call is made. The actual structure
elements will shortly go away.
