Third round of new stuff for IIO in the 3.16 cycle.

Browse Source 
This (rather late) set consists only of fixes to patches earlier in the
 cycle or minor fixes for other problems (such as randconfig build issues
 picked up by Arnd).  I've included the general minor fixes here as it is
 very late in the current cycle and they can all wait for the merge window.
 
 * Recent change to hid-sensors introduced a possible infinite loop due to a
   typo. In the same series, a report interval unit read was added but in the
   case where the hardware doesn't support it a value of 0 would lead to some
   nasty issues.  The patch sets it to the specified default of msecs.
 * Anon inodes were used by IIO without being explicitly selected.  This has
   been true for a long time so it clearly only effects rather unusual
   configurations (rand configs)
 * at91 requires the input subsytem but this wasn't explicity in the Kconfig.
 * A couple of parts supported by the max1363 driver were using the wrong
   iio_chan_spec arrays and hence would missreport their bit depths.  This has
   been there a long time and was never right so isn't a regression.
