Subject: [PATCH AUTOSEL 4.4 05/12] usb: host: ohci-tmio: check return value after calling platform_get_resource()
Date: Tue, 9 Nov 2021 17:24:19 -0500 [thread overview]
Message-ID: <20211109222426.1236575-5-sashal@kernel.org> (raw)
In-Reply-To: <20211109222426.1236575-1-sashal@kernel.org>
From: Yang Yingliang <yangyingliang@huawei.com>
[ Upstream commit 9eff2b2e59fda25051ab36cd1cb5014661df657b ]
It will cause null-ptr-deref if platform_get_resource() returns NULL,
we need check the return value.
