Subject: [PATCH 15/17] media: cros-ec-cec: Use cros_ec_send_cmd_msg()
Date: Thu, 30 Jan 2020 12:31:06 -0800 [thread overview]
Message-ID: <20200130203106.201894-16-pmalani@chromium.org> (raw)
In-Reply-To: <20200130203106.201894-1-pmalani@chromium.org>
Replace cros_ec_cmd_xfer_status() with cros_ec_send_cmd_msg() which does
the message buffer setup and cleanup, but is located in platform/chrome
and used by other drivers.
