[PATCH 1/2] ASoC: fsl_ssi: Remove an outdated comment

[Fabio Estevam]

The comment for the FSLSSI_I2S_RATES definition states that the
driver currently only supports I2S slave mode, which is no longer
correct.

Remove such outdated comment.

Applied "ASoC: fsl_ssi: Use the tolower() function" to the asoc tree

[Mark Brown]

The patch

   ASoC: fsl_ssi: Use the tolower() function

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

This part is still true, though, isn't it?

I have sent a v2 that keeps this part, but after thinking more about
it the "codec driver decide what rates are supported" part applies
only to SSI slave mode,
so IMHO we could just remove the entire comment.

Then why not remove FSLSSI_I2S_RATES altogether?
