[PATCH] Revert "ASoC: q6dsp: q6afe: remove unneeded dead-store initialization"
This reverts commit 5f1b95d08de712327e452d082a50fded435ec884.
The warnings that commit 5f1b95d08de7 ("ASoC: q6dsp: q6afe: remove unneeded dead-store initialization") was trying to fix were already fixed in commit 12900bacb4f3 ("ASoC: qcom: q6afe: remove useless assignments"). With both commits in the tree, port_id is uninitialized, as pointed out by clang:
sound/soc/qcom/qdsp6/q6afe.c:1213:18: warning: variable 'port_id' is uninitialized when used here [-Wuninitialized] stop->port_id = port_id; ^~~~~~~ sound/soc/qcom/qdsp6/q6afe.c:1186:13: note: initialize the variable 'port_id' to silence this warning int port_id; ^ = 0 1 warning generated.
Bring back the initialization so that everything works as intended.

Please submit patches using subject lines reflecting the style for the subsystem, this makes it easier for people to identify relevant patches. Look at what existing commits in the area you're changing are doing and make sure your subject lines visually resemble what they're doing. There's no need to resubmit to fix this alone.

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
