adau193x_reg_volatile() always return false. This seems pointless because current code uses REGCACHE_NONE cache_type which is supposed to be volatile.

The patch

ASoC: ssm2518: Drop .volatile_reg implementation

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

From: Axel Lin axel.lin@ingics.com Date: Tue, 20 Oct 2015 16:54:46 +0800 Subject: [PATCH] ASoC: ssm2518: Drop .volatile_reg implementation

The implementation of ssm2518_register_volatile always returns false, this behavior is the same as no .volatile_reg callback implementation when cache_type != REGCACHE_NONE.
