powerpc/nvram64: Need return the related error code on failure occurs When error occurs, need return the related error code to let upper caller know about it. ppc_md.nvram_size() can return the error code (e.g. core99_nvram_size() in 'arch/powerpc/platforms/powermac/nvram.c'). Also set ret value when only need it, so can save structions for normal cases. Signed-off-by: Chen Gang <gang.chen@asianux.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
