[SCSI] esp: Fix OOPS in esp_reset_cleanup().
OOPS reported by Friedrich Oslage <bluebird@porno-bullen.de> The problem here is that tp->starget is set every time a lun is allocated for a particular target so we can catch the sdev_target parent value. The reset handler uses the NULL'ness of this value to determine which targets are active. But esp_slave_destroy() does not NULL out this value when appropriate. So for every target that doesn't respond, the SCSI bus scan causes a stale pointer to be left here, with ensuing crashes like you're seeing. Signed-off-by: David S.
