Subject: [PATCHv2] media: dvb-frontends: Use kmemdup instead of duplicating its function
Date: Wed, 19 Sep 2018 13:26:43 +0800 [thread overview]
Message-ID: <1537334803-32592-1-git-send-email-zhongjiang@huawei.com> (raw)
kmemdup has implemented the function that kmalloc() + memcpy().
We prefer to kmemdup rather than code opened implementation.
