Subject: [PATCH 11/11] platform/chrome: cros_ec_proto: return -EPROTO if empty payload
Date: Wed, 15 Jun 2022 05:12:48 +0000 [thread overview]
Message-ID: <20220615051248.1628156-12-tzungbi@kernel.org> (raw)
In-Reply-To: <20220615051248.1628156-1-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.
