* Staging: IIO: Documentation: iio_utils: fix channel array generation.Michael Hennerich2011-03-091-23/+33
| | | | | | | | | | | | | | | | | | | | | | | The previous implementation flawed, in case some channels are not enabled. The sorted array would then include channel information of disabled channels, And misses the enabled ones, when the count is reached. More troublesome, the loop would not even terminate. The fix is twofold: First we skip channels that are not enabled. Then we use a tested bubble sort algorithm to sort the array. Since we already allocated exactly the number of bytes we need. We can exercise bubble sort on the original memory. In all cases I've seen, the array is already sorted, so this sort terminates immediately. Changes since V1: Fix coding style issues.

* IIO: Documentation: iio_utils: Prevent buffer overflowMichael Hennerich2011-02-281-1/+3
| | | | | | | | | | | | | | | 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.
