tools:iio:generic_buffer: fix check of errno

2015-05-31T16:35:04+00:00

Since errno contains the value of any of the defined error names, a
negation will not lead to the desired match.

tools:iio: save errno first

2015-05-31T16:32:44+00:00

The man-page of errno states, that errno should be saved before doing any
library call, as that call may have changed the value of errno. So, when
encountering any error, save errno first.
This patch affects generic_buffer.c, iio_event_monitor.c and iio_utils.c.

tools:iio: free channel-array completely

2015-05-31T16:20:16+00:00

In iio_utils.c build_channel_array() dynamically allocates the string
generic_name in the current iio_channel_info, which doesn't got freed in
case of an error.
This dynamically allocated channel-array is used by generic_buffer, and
needs to be freed on the error/exit path.
