The removal of HAVE_MEMBLOCK configuration option, mistakenly dropped the wrong #endif. This patch restores that #endif and removes the part that should have been actually removed, starting from #else and up to the correct #endif Reported-by: Jonathan Cameron <redacted> Signed-off-by: Mike Rapoport <redacted> --- drivers/of/fdt.c | 21 +-------------------- 1 file changed, 1 insertion(+), 20 deletions(-)
