PATCH 1/2 ASoC: rt286: Fix run time error while modifying const data

Make a copy of memory for index_cache rather than directly use the rt286_index_def to avoid run time error.

Fixes c418a84a8c8f ("ASoC: Constify reg_default tables")

PATCH 2/2 ASoC: rt298: Make rt298_index_def const

The index_cache is per instance run time state but rt298_index_def is not. Make rt298_index_def const and make a copy of memory for index_cache rather than directly use the rt298_index_def.

Applied "ASoC: rt286: Fix run time error while modifying const data" to the asoc tree

In reply to Axel Lin

The patch

ASoC: rt286: Fix run time error while modifying const data

has been applied to the asoc tree at

git://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
