### Description

In the Linux kernel, the following vulnerability has been resolved:scsi: target: core: Fix null-ptr-deref in target_alloc_device()There is a null-ptr-deref issue reported by KASAN:BUG: KASAN: null-ptr-deref in target_alloc_device+0xbc4/0xbe0 [target_core_mod]... kasan_report+0xb9/0xf0 target_alloc_device+0xbc4/0xbe0 [target_core_mod] core_dev_setup_virtual_lun0+0xef/0x1f0 [target_core_mod] target_core_init_configfs+0x205/0x420 [target_core_mod] do_one_initcall+0xdd/0x4e0... entry_SYSCALL_64_after_hwframe+0x76/0x7eIn target_alloc_device(), if allocing memory for dev queues fails, thendev will be freed by dev->transport->free_device(), but dev->transportis not initialized at that time, which will lead to a null pointerreference problem.Fixing this bug by freeing dev with hba->backend->ops->free_device().
