Subject: [SCSI] target: Fix memory leak on error path in pscsi_alloc_task
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8fc1858a42663248d5b362edc313786e0be7a639;p=linux-beck.git

[SCSI] target: Fix memory leak on error path in pscsi_alloc_task

If allocation of pt->pscsi_cdb fails, we need to free the just-allocated
pt or else it will be leaked.
