debugfs_create_dir() only returns an error pointer when kernel has been built without debugfs support. Quoting Documentation/filesystems/debugfs.txt:
"A NULL return value indicates that something went wrong. If ERR_PTR(-ENODEV) is returned, that is an indication that the kernel has been built without debugfs support and none of the functions described below will work."
As snd_soc_debugfs_init() is only defined when CONFIG_DEBUG_FS=y, there is no possibility for debugfs_create_dir() returning an error, so remove the unneeded error check.
