Subject: [PATCH] scsi: aic7xxx: use kmemdup
Date: Wed, 8 Jan 2020 19:29:53 +0800	[thread overview]
Message-ID: <20200108112953.41808-1-chenzhou10@huawei.com> (raw)

Fix memdup.cocci warnings:
./drivers/scsi/aic7xxx/aic79xx_core.c:9445:27-34: WARNING opportunity for kmemdup

Use kmemdup rather than duplicating its implementation.
