Commit r353569 in prerelease Clang-9 is producing a linkage failure: ld: drivers/net/wireless/intel/iwlwifi/fw/dbg.o: in function `_iwl_fw_dbg_apply_point': dbg.c:(.text+0x827a): undefined reference to `__compiletime_assert_2387' when the following configs are enabled: - CONFIG_IWLWIFI - CONFIG_IWLMVM - CONFIG_KASAN Work around the issue for now by marking the debug strings as `static`, which they probably should be any ways.
