Julia Lawall ce7c637a83 iio: potentiometer: merge calls to of_match_device and of_device_get_match_data
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

Jonathan Cameron 6d9d020da5 iio:dpot: drop assign iio_info.driver_module
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.
