Make use of arch_nvram_ops in device drivers so that the nvram_* function exports can be removed. Since they are no longer global symbols, rename the PPC32 nvram_* functions appropriately. Signed-off-by: Finn Thain --- Changed since v4: - Split off the CONFIG_PPC32, CONFIG_PPC_PMAC and CONFIG_NVRAM tests into a separate patch. --- arch/powerpc/kernel/setup_32.c | 8 ++++---- drivers/char/generic_nvram.c | 4 ++-- drivers/video/fbdev/controlfb.c | 4 ++-- drivers/video/fbdev/imsttfb.c | 4 ++-- drivers/video/fbdev/matrox/matroxfb_base.c | 2 +- drivers/video/fbdev/platinumfb.c | 4 ++-- drivers/video/fbdev/valkyriefb.c | 4 ++-- 7 files changed, 15 insertions(+), 15 deletions(-) Index: linux/arch/powerpc/kernel/setup_32.c =================================================================== --- linux.orig/arch/powerpc/kernel/setup_32.c 2015-08-23 20:41:11.000000000 +1000 +++ linux/arch/powerpc/kernel/setup_32.c 2015-08-23 20:41:14.000000000 +1000 @@ -170,20 +170,18 @@ __setup("l3cr=", ppc_setup_l3cr);
