Dan Carpenter eba97de9f8 scsi: mpt3sas: Fix double free in attach error handling ... commit ee560e7bba upstream. The caller also calls _base_release_memory_pools() on error so it leads to a number of double frees: drivers/scsi/mpt3sas/mpt3sas_base.c:7207 mpt3sas_base_attach() warn: 'ioc->chain_dma_pool' double freed drivers/scsi/mpt3sas/mpt3sas_base.c:7207 mpt3sas_base_attach() warn: 'ioc->hpr_lookup' double freed drivers/scsi/mpt3sas/mpt3sas_base.c:7207 mpt3sas_base_attach() warn: 'ioc->internal_lookup' double freed drivers/scsi/mpt3sas/mpt3sas_base.c:7207 mpt3sas_base_attach() warn: 'ioc->pcie_sgl_dma_pool' double freed drivers/scsi/mpt3sas/mpt3sas_base.c:7207 mpt3sas_base_attach() warn: 'ioc->reply_dma_pool' double freed drivers/scsi/mpt3sas/mpt3sas_base.c:7207 mpt3sas_base_attach() warn: 'ioc->reply_free_dma_pool' double freed drivers/scsi/mpt3sas/mpt3sas_base.c:7207 mpt3sas_base_attach() warn: 'ioc->reply_post_free_array_dma_pool' double freed drivers/scsi/mpt3sas/mpt3sas_base.c:7207 mpt3sas_base_attach() warn: 'ioc->reply_post_free_dma_pool' double freed drivers/scsi/mpt3sas/mpt3sas_base.c:7207 mpt3sas_base_attach() warn: 'ioc->sense_dma_pool' double freed Fixes: 74522a92bb ("scsi: mpt3sas: Optimize I/O memory consumption in driver.")
