Subject: [PATCH 4/9] mtd: nandsim: use random32_get_bytes
Date: Sun, 28 Oct 2012 16:19:01 +0900 [thread overview]
Message-ID: <1351408746-8623-4-git-send-email-akinobu.mita@gmail.com> (raw)
In-Reply-To: <1351408746-8623-1-git-send-email-akinobu.mita@gmail.com>
This also removes unnecessary memset call which is immediately overwritten
with random bytes.
