Subject: [PATCH 07/11] platform/chrome: cros_ec_proto: return -EAGAIN when retries timed out
Date: Wed, 15 Jun 2022 05:12:44 +0000 [thread overview]
Message-ID: <20220615051248.1628156-8-tzungbi@kernel.org> (raw)
In-Reply-To: <20220615051248.1628156-1-tzungbi@kernel.org>
While EC_COMMS_STATUS_PROCESSING flag is still on after it tries
EC_COMMAND_RETRIES times for sending EC_CMD_GET_COMMS_STATUS,
cros_ec_wait_until_complete() doesn't return an error code.
Return -EAGAIN in the case instead.
