Subject: [PATCH] modpost: add NOFAIL to strdup call
Date:   Tue, 15 Oct 2019 09:49:06 +0300
Message-Id: <20191015064906.13833-1-efremov@linux.com>
MIME-Version: 1.0

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add NOFAIL check for the strdup call, since the function
allocates memory and can return NULL. All strdup calls in
modpost are checked with NOFAIL.
