If anyone has any objections, please let me know. ------------------ From: Srinivas Kandagatla [ Upstream commit 8167f4f42572818fa8153be2b03e4c2120846603 ] Qcom lpass is using component->id to keep DAI ID (A). (S) static int lpass_platform_pcmops_open( sruct snd_soc_component *component, struct snd_pcm_substream *substream) { ^^^^^^^^^(B0) ... (B1) struct snd_soc_pcm_runtime *soc_runtime = snd_soc_substream_to_rtd(substream); (B2) struct snd_soc_dai *cpu_dai = snd_soc_rtd_to_cpu(soc_runtime, 0); ... (B3) unsigned int dai_id = cpu_dai->driver->id; (A) component->id = dai_id; ... } This driver can get dai_id from substream (B0 - B3). In this driver, below functions get dai_id from component->id (A). (X) lpass_platform_pcmops_suspend() (Y) lpass_platform_pcmops_resume() (Z) lpass_platform_copy() Here, (Z) can get it from substream (B0 - B3), don't need to use component->id (A). On suspend/resume (X)(Y), dai_id can only be obtained from component->id (A), because there is no substream (B0) in function parameter. But, component->id (A) itself should not be used for such purpose. It is intilialized at snd_soc_component_initialize(), and parsed its ID (= component->id) from device name (a). int snd_soc_component_initialize(...) { ... if (!component->name) { (a) component->name = fmt_single_name(dev, &component->id); ... ^^^^^^^^^^^^^ } ... } Unfortunately, current code is broken to start with. There are many regmaps that the driver cares about, however its only managing one (either dp or i2s) in component suspend/resume path. I2S regmap is mandatory however other regmaps are setup based on flags like "hdmi_port_enable" and "codec_dma_enable". Correct thing for suspend/resume path to handle is by checking these flags, instead of using component->id.
