[PATCH][next] ASoC: rt715: Make read-only arrays capture_reg_H and capture_reg_L static const
Don't populate the read-only arrays capture_reg_H and capture_reg_L on the stack but instead make them static const. Also makes the object code a little smaller.

[1/1] ASoC: rt715: Make read-only arrays capture_reg_H and capture_reg_L static const commit: b5d5051971b44c9952b62f261509cf837b9d21ba
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
