It is. But it might make sense to re-order the code to look like

    case 54000000:
        if (source != ADAV80X_PLL_SRC_XIN)
            return -EINVAL;

        pll_ctrl1 |= ADAV80X_PLL_CTRL1_PLLDIV;
        break;

It is just as many lines added when adding the /* fall through */, but it makes it more obvious what is going on.

Either way:

Yes, it's much more obvious.

The patch

ASoC: adav80x: mark expected switch fall-through

has been applied to the asoc tree at

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

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
