Subject: [PATCH 3/9] ALSA: hda/cs35l56: Call cs_dsp_power_down() before reloading firmware
Date: Mon, 31 Jul 2023 17:57:20 +0100 [thread overview]
Message-ID: <20230731165726.7940-4-rf@opensource.cirrus.com> (raw)
In-Reply-To: <20230731165726.7940-1-rf@opensource.cirrus.com>
When firmware is reloaded after a system resume cs_dsp_power_down() should
be called before calling cs_dsp_power_up().
The fw_patched flag should also be cleared and only set again if the
firmware download succeeded.
