In the Linux kernel, the following vulnerability has been resolved: nfp:
flower: handle acti_netdevs allocation failure The kmalloc_array() in
nfp_fl_lag_do_work() will return null, if the physical memory has run out.
As a result, if we dereference the acti_netdevs, the null pointer
dereference bugs will happen. This patch adds a check to judge whether
allocation failure occurs. If it happens, the delayed work will be
rescheduled and try again.
