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 drivers/iio/accel/kxsd9-spi.ko | grep alias
alias: spi:kxsd9
After this patch:
modinfo drivers/iio/accel/kxsd9-spi.ko | grep alias
alias: spi:kxsd9
alias: of:N*T*Ckionix,kxsd9C*
alias: of:N*T*Ckionix,kxsd9
