regcache_maple_sync() tries to sync all cached values no matter whether it's writable or not. OTOH, regache_sync_val() does care the wrtability and returns -EIO for a read-only register. This results in an error message like: snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x2f0009. -5 and the sync loop is aborted incompletely.

[1/1] regmap: regcache: Don't sync read-only registers commit: 44e46572f0bae431a6092e3cfd2f47bff8b8d18c
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
