4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Arnd Bergmann <arnd@xxxxxxxx> commit b7e2d195cc523bd92ed7a64aac089421dbab2a2d upstream. The SoC variant of the ssb code is now optional like the other ones, which means we can build the framwork without any front-end, but that results in a warning: drivers/ssb/main.c:616:12: warning: 'ssb_bus_register' defined but not used [-Wunused-function] This annotates the ssb_bus_register function as __maybe_unused to shut up the warning. A configuration like this will not work on any hardware of course, but we still want this to silently build without warnings if the configuration is allowed in the first place.
