Subject: [PATCH AUTOSEL 5.4 08/30] usb: musb: tusb6010: check return value after calling platform_get_resource()
Date: Tue, 9 Nov 2021 17:22:02 -0500 [thread overview]
Message-ID: <20211109222224.1235388-8-sashal@kernel.org> (raw)
In-Reply-To: <20211109222224.1235388-1-sashal@kernel.org>
From: Yang Yingliang <yangyingliang@huawei.com>
[ Upstream commit 14651496a3de6807a17c310f63c894ea0c5d858e ]
It will cause null-ptr-deref if platform_get_resource() returns NULL,
we need check the return value.
