Revision 00b39f698a4f1ee897227cace2e3937fc4412270 authored by Stefan Haberland on 19 December 2019, 08:43:51 UTC, committed by Jens Axboe on 20 December 2019, 18:52:01 UTC
If for whatever reason the dasd_eckd_check_characteristics() function
exits after at least some paths have their configuration data
allocated those data is never freed again. In the error case the
device->private pointer is set to NULL and dasd_eckd_uncheck_device()
will exit without freeing the path data because of this NULL pointer.

Fix by calling dasd_eckd_clear_conf_data() for error cases.

Also use dasd_eckd_clear_conf_data() in dasd_eckd_uncheck_device()
to avoid code duplication.
