The "dai_id" given into LPAIF_INTFDMA_REG(...) is already the real DAI ID, not an index into v->dai_driver. Looking it up again seems entirely redundant.
For IPQ806x (and SC7180 since commit 09a4f6f5d21c ("ASoC: dt-bindings: lpass: Fix and common up lpass dai ids") this is now often an out-of-bounds read because the indexes in the "dai_driver" array no longer match the actual DAI ID.

Thanks!

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
