has been applied to the asoc tree at


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.

Subject: [PATCH] ASoC: ssm4567: Add OF device ID table

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

Before this patch:

$ modinfo sound/soc/codecs/snd-soc-ssm4567.ko | grep alias
alias:          acpi*:INT343B:*
alias:          i2c:ssm4567

After this patch:

$ modinfo sound/soc/codecs/snd-soc-ssm4567.ko | grep alias
alias:          acpi*:INT343B:*
alias:          of:N*T*Cadi,ssm4567C*
alias:          of:N*T*Cadi,ssm4567
alias:          i2c:ssm4567
