The patch
ASoC: arizona: fix range of OPCLK_REF
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: Richard Fitzgerald rf@opensource.wolfsonmicro.com Date: Tue, 3 Nov 2015 14:24:12 +0000 Subject: [PATCH] ASoC: arizona: fix range of OPCLK_REF
The code was able to generate illegal OPCLK_REF values because the reference frequency tables listed all values of SYSCLK instead of valid values for OPCLK_REF clock. The maximum OPCLK_REF clock is 49.152MHz or 45.1584MHz.
