Subject: [PATCH v2 10/10] platform/chrome: cros_ec_proto: return -EPROTO if empty payload
Date: Mon, 18 Jul 2022 05:09:14 +0000 [thread overview]
Message-ID: <20220718050914.2267370-11-tzungbi@kernel.org> (raw)
In-Reply-To: <20220718050914.2267370-1-tzungbi@kernel.org>
cros_ec_wait_until_complete() sends EC_CMD_GET_COMMS_STATUS which expects
to receive sizeof(struct ec_response_get_comms_status) from
cros_ec_xfer_command().
Return -EPROTO if cros_ec_xfer_command() returns 0.
Reviewed-by: Guenter Roeck <groeck@chromium.org>
