drivers/staging/lustre/lustre/llite/xattr.c:199:2-7: WARNING: NULL check before
freeing functions like kfree, debugfs_remove, debugfs_remove_recursive or
usb_free_urb is not needed. Maybe consider reorganizing relevant code to avoid
passing NULL values.
NULL check before some freeing functions is not needed.
Based on checkpatch warning
"kfree(NULL) is safe this check is probably not required"
and kfreeaddr.cocci by Julia Lawall.
