+Subject: [PATCH] ASoC: qcom: lpass-cpu: Fix fallback SD line index handling
+
+[[ Submitted upstream as:
+ https://lore.kernel.org/all/20221231061545.2110253-1-computersforpeace@gmail.com/
+ Currently queued for -next (v6.3?) as:
+ 000bca8d706d ASoC: qcom: lpass-cpu: Fix fallback SD line index handling
+]]
+
+These indices should reference the ID placed within the dai_driver
+array, not the indices of the array itself.
+
+This fixes commit 4ff028f6c108 ("ASoC: qcom: lpass-cpu: Make I2S SD
+lines configurable"), which among others, broke IPQ8064 audio
+(sound/soc/qcom/lpass-ipq806x.c) because it uses ID 4 but we'd stop
+initializing the mi2s_playback_sd_mode and mi2s_capture_sd_mode arrays
+at ID 0.
+
