If anyone has any objections, please let me know. ------------------ From: Fabio Estevam commit 8d8d7c1dbc46aa07a76acab7336a42ddd900be10 upstream. The IIO core issues warnings when a scan mask is a subset of a previous entry in the available_scan_masks array. On a board using a MAX11601, the following warning is observed: max1363 1-0064: available_scan_mask 7 subset of 6. Never used This occurs because the entries in the max11607_mode_list[] array are not ordered correctly. To fix this, reorder the entries so that no scan mask is a subset of an earlier one. While at it, reorder the mode_list[] arrays for other supported chips as well, to prevent similar warnings on different variants. Note fixes tag dropped as these were introduced over many commits a long time back and the side effect until recently was a reduction in sampling rate due to reading too many channels when only a few were desired. Now we have a sanity check that reports this error but that is not where the issue was introduced.
