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.
