This is a quick fix for the below two issues when building spdif as modules. 1) If modprobing modules in order: (Step 1) snd-soc-fsl-spdif -> (Step 2) snd-soc-imx-spdif -> (Step 3) snd-soc-spdif-tx/rx, we will fail to create imx-spdif card and dai link unless we rmmod snd-soc-imx-spdif and modprobe it again due to the execution platform_driver_unregister() in probe() when meeting -EPROBE_DEFER at Step 2. 2) After "imx-spdif sound-spdif.17: dit-hifi <-> 2004000.spdif mapping ok", 'rmmod snd-soc-imx-spdif' would cause kernel dump with warning: WARNING: CPU: 0 PID: 1301 at /home/rmk/git/linux-rmk/fs/sysfs/dir.c:915 sysfs_hash_and_remove+0x84/0x90() sysfs: can not remove 'dapm_widget', no directory This should be caused by disordered resourse releasing of the whole link. And trying to unregister the card and then CODEC dev can't fix this issue. Thus this patch just provides a simple fix to these two bugs by using the snd-soc-dummy in the core instead of seperate snd-soc-spdif-tx/rx so that there's no need to handle the registering and unregistering of CODEC or CODEC dai any more.
