PVS-Studio warning V595 for MAME

static void find_software_item(....)
{
  char *software_list_ptr = NULL;
  ...
  *software_list_ptr =
    software_list_open( options, swlist_name, FALSE, NULL );
  if ( software_list_ptr )
  {
    *software_info_ptr =
      software_list_find( *software_list_ptr, swname, NULL );
  ...
}

Most likely this is what should be written here: if ( *software_list_ptr )

This suspicious code was found in MAME project by PVS-Studio static code analyzer.
Warning message is:
V595 The 'software_list_ptr' pointer was utilized before it was verified against nullptr. Check lines: 1586, 1591.  softlist.c 1586
