ASoc: rt5645: 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-rt5645.ko | grep alias
alias: acpi*:10EC3270:*
alias: acpi*:10EC5640:*
alias: acpi*:10EC5650:*
alias: acpi*:10EC5648:*
alias: acpi*:10EC5645:*
alias: i2c:rt5650
alias: i2c:rt5645
After this patch:
$ modinfo sound/soc/codecs/snd-soc-rt5645.ko | grep alias
