Subject: [PATCH AUTOSEL 5.10 09/38] USB: host: isp116x: check return value after calling platform_get_resource()
Date: Tue,  7 Jun 2022 13:58:04 -0400	[thread overview]
Message-ID: <20220607175835.480735-9-sashal@kernel.org> (raw)
In-Reply-To: <20220607175835.480735-1-sashal@kernel.org>

From: Zhen Ni <nizhen@uniontech.com>

[ Upstream commit 134a3408c2d3f7e23eb0e4556e0a2d9f36c2614e ]

It will cause null-ptr-deref if platform_get_resource() returns NULL,
we need check the return value.
