Subject: [PATCH v2 1/1] scsi: pm8001: remove unnecessary oom message
Date: Thu, 10 Jun 2021 17:46:05 +0800 [thread overview]
Message-ID: <20210610094605.16672-2-thunder.leizhen@huawei.com> (raw)
In-Reply-To: <20210610094605.16672-1-thunder.leizhen@huawei.com>
Fixes scripts/checkpatch.pl warning:
WARNING: Possible unnecessary 'out of memory' message
Remove it can help us save a bit of memory.
By the way, change the return error code from "-1" to "-ENOMEM".
