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

Posting a series of fixes about potential null pointer accesses.

Changes from v3:
- Dropped net/tap: check if name is null
- Moved the comment to the appropriate position in ethdev: check return result of rte_eth_dev_info_get

Changes from v2:
- Remove braces around single line statements
- use NULL comparisons


Sinan Kaya (10):
  ethdev: check return result of rte_eth_dev_info_get
  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
