Subject: [PATCH 4.14 10/62] st_nci_hci_connectivity_event_received: null check the allocation
Date: Tue, 27 Aug 2019 09:50:15 +0200 [thread overview]
Message-ID: <20190827072700.989331884@linuxfoundation.org> (raw)
In-Reply-To: <20190827072659.803647352@linuxfoundation.org>
[ Upstream commit 3008e06fdf0973770370f97d5f1fba3701d8281d ]
devm_kzalloc may fail and return NULL. So the null check is needed.
