[PATCH] ASoC: fsl_sai: fix getting version from VERID
The version information is at the bit31 ~ bit16 in the VERID register, so need to right shift 16bit to get it, otherwise the result of comparison "sai->verid.version >= 0x0301" is wrong.

I would put the version in one line, but probably is easier to read this way. Also, please explain, in commit message, what and from where is 0x0301 - might worth adding a macro for this, in another commit, of course. Otherwise,

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
