[PATCH 5.8 071/232] appletalk: Fix atalk_proc_init() return path

[Greg Kroah-Hartman]

From: Vincent Duvert <vincent.l...@duvert.net>

commit d0f6ba2ef2c1c95069509e71402e7d6d43452512 upstream.

Add a missing return statement to atalk_proc_init so it doesn't return
-ENOMEM when successful.  This allows the appletalk module to load
properly.

Fixes: e2bcd8b0ce6e ("appletalk: use remove_proc_subtree to simplify procfs 
code")
