Subject: [PATCH 08/10] mfd: cros_ec: Use kzalloc and cros_ec_cmd_xfer_status helper
Date: Tue, 4 Jun 2019 17:20:17 +0200 [thread overview]
Message-ID: <20190604152019.16100-9-enric.balletbo@collabora.com> (raw)
In-Reply-To: <20190604152019.16100-1-enric.balletbo@collabora.com>
This patch makes use of cros_ec_cmd_xfer_status() instead of
cros_ec_cmd_xfer() so we can remove some redundant code. It also uses
kzalloc instead of kmalloc so we can remove more redundant code.
