This patch fixes sparse warnings due non declarations of static functions. arch/arm/mach-omap2/timer-gp.c:115:12: warning: symbol 'omap2_gp_clockevent_set_gptimer' was not declared. Should it be static? arch/arm/mach-omap2/powerdomain.c:993:5: warning: symbol 'pwrdm_set_lowpwrstchange' was not declared. Should it be static? arch/arm/mach-omap2/board-flash.c:141:8: warning: symbol 'board_nand_init' was not declared. Should it be static? arch/arm/mach-omap2/board-n8x0.c:416:6: warning: symbol 'n8x0_mmc_slot1_cover_handler' was not declared. Should it be static? arch/arm/mach-omap2/board-n8x0.c:544:13: warning: symbol 'n8x0_mmc_init' was not declared. Should it be static? arch/arm/mach-omap2/board-rx51-peripherals.c:902:13: warning: symbol 'rx51_peripherals_init' was not declared.
