Subject: net: octeontx2: NULL check before dereference
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=425f9839f3c2922a36efaefa53833f0abe681be0;p=pandora-u-boot.git

net: octeontx2: NULL check before dereference

In rvu_af_init if the code fails to allocate memory for nix_af it will
take the error path with nix_af == NULL which will dereference nix_af.
Add the appropriate NULL check.

This issue was found by Smatch.
