Subject: [PATCH 4.4 07/77] st21nfca_connectivity_event_received: null check the allocation
Date: Wed, 4 Sep 2019 19:52:54 +0200 [thread overview]
Message-ID: <20190904175304.202208742@linuxfoundation.org> (raw)
In-Reply-To: <20190904175303.317468926@linuxfoundation.org>
[ Upstream commit 9891d06836e67324c9e9c4675ed90fc8b8110034 ]
devm_kzalloc may fail and return null. So the null check is needed.
