From 6f02bdfc995f098bde87216c122ade2b46f971b5 Mon Sep 17 00:00:00 2001 From: Denis Efremov Date: Tue, 27 Aug 2019 15:20:23 +0300 Subject: modpost: add NOFAIL to strndup Add NOFAIL check for the strndup call, because the function allocates memory and can return NULL. All calls to strdup in modpost are checked with NOFAIL.
