[alsa-devel] [PATCH] ASoC: wm8983: Get rid of wm8983_access_masks table
The max8983_access table is used for look up readable/writable attributes of registers. The writable registers are mostly in continuous ranges, so we can replace max8983_access table by using case range. The read fields are all 0, so just drop implement of .readable callback.
Also set .max_register setting.

The patch
ASoC: wm8983: Get rid of wm8983_access_masks table
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
