From 0f4bb10857e22a657e6c8cca5d1d54b641e94628 Mon Sep 17 00:00:00 2001 From: Wen Yang Date: Thu, 6 Dec 2018 07:29:10 -0500 Subject: media: siano: Use kmemdup instead of duplicating its function kmemdup has implemented the function that kmalloc() + memcpy(). We prefer to kmemdup rather than code opened implementation. This issue was detected with the help of coccinelle.
