Subject: [PATCH v2 1/7] usb: typec: ucsi: move ucsi_acknowledge() from ucsi_read_error()
Date: Fri, 21 Jun 2024 01:55:20 +0300	[thread overview]
Message-ID: <20240621-ucsi-rework-interface-v2-1-a399ff96bf88@linaro.org> (raw)
In-Reply-To: <20240621-ucsi-rework-interface-v2-0-a399ff96bf88@linaro.org>

As a preparation for reworking UCSI command handling, move
ucsi_acknowledge() for the failed command from ucsi_read_error() to
ucsi_exec_command().
