Commit Message

Daniel G April 22, 2019, 7:12 p.m. UTC
Add missing <of_device_id> table for SPI driver relying on SPI
device match since compatible is in a DT binding or in a DTS.

Before this patch:
modinfo sound/soc/codecs/snd-soc-adau1977-spi.ko | grep alias
alias:          spi:adau1979
alias:          spi:adau1978
alias:          spi:adau1977

After this patch:
modinfo sound/soc/codecs/snd-soc-adau1977-spi.ko | grep alias
alias:          of:N*T*Cadi,adau1979C*
alias:          of:N*T*Cadi,adau1979
alias:          of:N*T*Cadi,adau1978C*
alias:          of:N*T*Cadi,adau1978
alias:          of:N*T*Cadi,adau1977C*
alias:          of:N*T*Cadi,adau1977
alias:          spi:adau1979
alias:          spi:adau1978
alias:          spi:adau1977
