ASoC: pcm186x: Fix device reset-registers trigger value

According to the current device datasheet (TI Lit # SLAS831D, revised March 2018) the value written to the device's PAGE register to trigger a complete register reset should be 0xfe, not 0xff. So go ahead and update to the correct value.

Does 0xff not reset the device? If so then this is not just a typo but a bug and this patch should have a fixes tag. Either way:

The patch

ASoC: pcm186x: Fix device reset-registers trigger value

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
