Subject[PATCH] [v2] scsi: scsi_debug: Fix memleak in scsi_debug_init
Date
When sdeb_zbc_model does not match BLK_ZONED_NONE,
BLK_ZONED_HA or BLK_ZONED_HM, we should free sdebug_q_arr
to prevent memleak. Also there is no need to execute
sdebug_erase_store() on failure of sdeb_zbc_model_str().

Changelog:

v2: - Add missed assignment statement for ret.
