Following up the codeql reported problems first submitted
by Stephen Hemminger here:

https://lore.kernel.org/all/20220527161210.77212d0b@hermes.local/t/

Posting a series of fixes about potential null pointer accesses.

Changes from v1:
- Remove braces around single line statements
- use NULL comparisons

Sinan Kaya (11):
  ethdev: check return result of rte_eth_dev_info_get
  net/tap: check if name is null
  memzone: check result of rte_fbarray_get
  memzone: check result of malloc_elem_from_data
  malloc: malloc_elem_join_adjacent_free can return null
  malloc: check result of rte_mem_virt2memseg_list
  malloc: check result of rte_fbarray_get
  malloc: check result of rte_mem_virt2memseg
  malloc: check result of malloc_elem_free
  malloc: check result of elem_start_pt
  bus/vdev: check result of rte_vdev_device_name
