Subject: [PATCH 2/3] ata: ahci_platform: convert kzallloc to kcalloc
Date: Thu, 12 Jul 2018 11:41:30 +0000 [thread overview]
Message-ID: <1531395691-4653-3-git-send-email-clabbe@baylibre.com> (raw)
In-Reply-To: <1531395691-4653-1-git-send-email-clabbe@baylibre.com>
It's better to kcalloc instead of kzalloc(n * sizeof())
