From de6cdcb5ce504c9d346858569e4ad2ca3ac2fe45 Mon Sep 17 00:00:00 2001 From: Muhammad Falak R Wani Date: Mon, 23 May 2016 16:24:31 -0700 Subject: [PATCH] drivers/memstick/core/mspro_block: use kmemdup Use kmemdup when some other buffer is immediately copied into allocated region. It replaces call to allocation followed by memcpy, by a single call to kmemdup.
