Subject: [PATCH 6/9] ALSA: hda/cs35l56: cs_dsp_power_down() on cs35l56_hda_fw_load() error path
Date:   Mon, 31 Jul 2023 17:57:23 +0100
Message-ID: <20230731165726.7940-7-rf@opensource.cirrus.com>

If cs35l56_hda_fw_load() successfully called cs_dsp_power_up() the error
path must balance that with a call to cs_dsp_power_down().
