scsi: iscsi: qla4xxx: fix double free in probe
On this error path we call qla4xxx_mem_free() and then the caller also calls qla4xxx_free_adapter() which calls qla4xxx_mem_free(). It leads to a couple double frees: drivers/scsi/qla4xxx/ql4_os.c:8856 qla4xxx_probe_adapter() warn: 'ha->chap_dma_pool' double freed drivers/scsi/qla4xxx/ql4_os.c:8856 qla4xxx_probe_adapter() warn: 'ha->fw_ddb_dma_pool' double freed Fixes: afaf5a2d341d ("[SCSI] Initial Commit of qla4xxx") Link: https://lore.kernel.org/r/20191203094421.hw7ex7qr3j2rbsmx@kili.mountain Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Martin K.
