Subject: [PATCH 4.13 24/52] libnvdimm, btt: check memory allocation failure
Date: Mon, 18 Sep 2017 11:09:52 +0200 [thread overview]
Message-ID: <20170918090907.591246907@linuxfoundation.org> (raw)
In-Reply-To: <20170918090904.072766209@linuxfoundation.org>
4.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christophe Jaillet <christophe.jaillet@wanadoo.fr>
commit ed36b4dba54a421ce5551638f6a9790b2c2116b1 upstream.
Check memory allocation failures and return -ENOMEM in such cases, as
already done few lines below for another memory allocation.
This avoids NULL pointers dereference.
Fixes: 14e494542636 ("libnvdimm, btt: BTT updates for UEFI 2.7 format")
