+Subject: appletalk: Fix compile regression
+
+[ Upstream commit 27da0d2ef998e222a876c0cec72aa7829a626266 ]
+
+A bugfix just broke compilation of appletalk when CONFIG_SYSCTL
+is disabled:
+
+In file included from net/appletalk/ddp.c:65:
+net/appletalk/ddp.c: In function 'atalk_init':
+include/linux/atalk.h:164:34: error: expected expression before 'do'
+ #define atalk_register_sysctl()  do { } while(0)
+                                  ^~
+net/appletalk/ddp.c:1934:7: note: in expansion of macro 'atalk_register_sysctl'
+  rc = atalk_register_sysctl();
+
+This is easier to avoid by using conventional inline functions
+as stubs rather than macros. The header already has inline
+functions for other purposes, so I'm changing over all the
+macros for consistency.
