Subject: [PATCH] ieee1275/ofnet: Fix grub_malloc() removed after added safe
math functions
grub_malloc() has been inadvertently removed from the ieee1275/ofnet
code after it has been modified to use safe match function.
Fixes: 4beeff8a (net: Use safe math macros to prevent overflows)
Tested-by: Marta Lewandowska <mlewando@redhat.com>
