52b31bcc93 iio:adc: drop assign iio_info.driver_module and iio_trigger_ops.owner
The equivalent of both of these are now done via macro magic when
the relevant register calls are made.  The actual structure
elements will shortly go away.

52ceb7731e iio: adc: men_z188_adc: constify iio_info structures
Check for iio_info structures that are only stored in the info field of a
iio_dev structure.  This field is declared const, so iio_info structures
that have this property can be declared as const also.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r disable optional_qualifier@
identifier i;
position p;
@@
static struct iio_info i@p = { ... };

@ok@
identifier r.i;
struct iio_dev e;
position p;
@@
e.info = &i@p;

@bad@
position p != {r.p,ok.p};
identifier r.i;
struct iio_info e;
@@
e@i@p

@depends on !bad disable optional_qualifier@
identifier r.i;
@@
static
+const
 struct iio_info i = { ... };
// </smpl>

The result of size on this file before the change is:
   text	      data     bss     dec         hex	  filename
   1529	       312       0    1841         731
   drivers/iio/adc/men_z188_adc.o

and after the change it is:
   text	     data        bss	    dec	    hex	filename
   1689       168          0       1857     741
