Subject: [PATCH v3 1/8] pstore: Replace four kzalloc() calls by kcalloc() in ramoops_init_przs()
Date: Tue, 18 Oct 2016 16:13:27 +0900 [thread overview]
Message-ID: <1476774814-6840-2-git-send-email-nobuhiro.iwamatsu.kw@hitachi.com> (raw)
In-Reply-To: <1476774814-6840-1-git-send-email-nobuhiro.iwamatsu.kw@hitachi.com>
The script "checkpatch.pl" can point information out like the following.
WARNING: Prefer kcalloc over kzalloc with multiply
Thus fix the affected source code places.
