commit d65283f7b695b5 added mod->arch.secstr under CONFIG_ARC_DW2_UNWIND, but used it unconditionally which broke builds when the option was disabled. Fix that by adjusting the #ifdef guard. And while at it add a missing guard (for unwinder) in module.c as well Reported-by: Waldemar Brodkorb <wbx@openadk.org> Cc: <stable@vger.kernel.org [4.9]> Fixes: d65283f7b695b5 ("ARC: module: elide loop to save reference to .eh_frame") Signed-off-by: Vineet Gupta <vgupta@synopsys.com> --- arch/arc/include/asm/module.h | 4 ++-- arch/arc/kernel/module.c | 4 +++- 2 files changed, 5 insertions(+), 3 deletions(-)
