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.
