Sam Protsenko feaa7856f5 dfu: Fix data abort in dfu_free_entities() ... Commit 5d8fae7916 ("dfu: avoid memory leak") brings a regression which described below. This patch is effectively reverting that commit, adding corresponding comment to avoid such regressions in future. In case of error in dfu_config_entities(), it frees "dfu" array, which leads to "data abort" in dfu_free_entities(), which tries to free the same array (and even tries to access it from linked list first). The issue occurs e.g. when partition table on device does not match $dfu_alt_info layout: => dfu 0 mmc 1 Couldn't find part #2 on mmc device #1 DFU entities configuration failed! data abort To fix this issue, do not free "dfu" array in dfu_config_entities(). It will be freed later in dfu_free_entities(). Tested on BeagleBone Black (where this regression was originally found).
