Subject: [PATCH 02/17] platform/chrome: chardev: Use send_cmd_msg()
Date: Thu, 30 Jan 2020 12:30:35 -0800 [thread overview]
Message-ID: <20200130203106.201894-3-pmalani@chromium.org> (raw)
In-Reply-To: <20200130203106.201894-1-pmalani@chromium.org>
Update the Chrome OS character device driver to use the newly introduced
cros_ec_send_cmd_msg() function instead of cros_ec_cmd_xfer_status(),
thus avoiding message buffer set up work which is already done by the
new function.
