CC arch/arm/mach-omap2/timer.o arch/arm/mach-omap2/timer.c:395:19: warning: ‘omap2_sync32k_clocksource_init’ defined but not used [-Wunused-function] This issue was introduced by commit 6f80b3b (ARM: OMAP2+: timer: remove CONFIG_OMAP_32K_TIMER) where the omap2_sync32k_clocksource_init() is no longer referenced by the timer initialisation function for the AM335x device as it has no 32k-sync timer. Fix this by adding the "__maybe_unused" compiler directive to the omap2_sync32k_clocksource_init() function to indicate that this function may be used for certain configurations.
