The patch
ASoC: wcd9335: fix address map representation
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

slimbus addresses are 16 bit wide, masking page numbers to wcd register at offset of 12 will limit the number for pages. So it becomes impossible to write to page 0x10 registers. Remove masking 0x800 (slimbus address range) from register address and making use of window parameters in regmap config should fix it and also will represent the registers exactly inline with Datasheet.
Remove this unnessary masking and make the registers be inline with datasheet.
