Michael Hennerich fc7f95a946 IIO: Documentation: iio_utils: fix mask generation
Variable sizeint is used uninitialized.
Remove sizeint completely and use bits_used instead.

Michael Hennerich 7ccd4506fa IIO: Documentation: iio_utils: Prevent buffer overflow
The first part of build_channel_array()identifies the number of enabled channels.
Further down this count is used to allocate the ci_array. The next section parses the
scan_elements directory again, and fills ci_array regardless if the channel is enabled or not.
So if less than available channels are enabled ci_array memory is overflowed.

This fix makes sure that we allocate enough memory. But the whole approach looks a bit
cumbersome to me. Why not allocate memory for MAX_CHANNLES, less say 64
(I never seen a part with more than that channels). And skip the first part entirely.

Jonathan Cameron e58537ccce staging: iio: update example application.
The application is now considerably more generic and should cope
with all devices in tree.  The process function will need to be
extended to handle other type values as needed.
