Subject: [PATCH net-next v2 2/4] ptp: ocp: Fix error path for pci_ocp_device_init()
Date: Mon, 16 Aug 2021 15:13:35 -0700 [thread overview]
Message-ID: <20210816221337.390645-3-jonathan.lemon@gmail.com> (raw)
In-Reply-To: <20210816221337.390645-1-jonathan.lemon@gmail.com>
If ptp_ocp_device_init() fails, pci_disable_device() is skipped.
Fix the error handling so this case is covered. Update ptp_ocp_remove()
so the normal exit path is identical.
Reported-by: Hulk Robot <hulkci@huawei.com>
Fixes: 773bda964921 ("ptp: ocp: Expose various resources on the
timecard.")
