Subject: [PATCH net v1] hinic: fix passing non negative value to ERR_PTR
Date: Wed, 1 Jul 2020 11:16:33 +0800 [thread overview]
Message-ID: <20200701031633.24249-1-luobin9@huawei.com> (raw)
get_dev_cap and set_resources_state functions may return a positive
value because of hardware failure, and the positive return value
can not be passed to ERR_PTR directly.
Fixes: 7dd29ee12865 ("hinic: add sriov feature support")
Signed-off-by: Luo bin <luobin9@huawei.com>
