Subject: [PATCH] objtool: Add a missing comma to avoid string concatenation
Date: Wed, 15 Dec 2021 11:38:40 -0600	[thread overview]
Message-ID: <874k79sr8f.fsf_-_@email.froward.int.ebiederm.org> (raw)
In-Reply-To: <db094a6d-48d6-7641-b8c3-fc338bd779b0@intel.com>

[-- Attachment #1: Type: text/plain, Size: 1394 bytes --]


Recently the kbuild robot reported two new errors:

>> lib/kunit/kunit-example-test.o: warning: objtool: .text.unlikely: unexpected end of section
>> arch/x86/kernel/dumpstack.o: warning: objtool: oops_end() falls through to next function show_opcodes()

I don't know why they did not occur in my test setup but after digging
it I realized I had accidentally dropped a comma in
tools/objtool/check.c when I renamed rewind_stack_do_exit to
rewind_stack_and_make_dead.

Add that comma back to fix objtool errors.

Reported-by: kernel test robot <lkp@intel.com>

For the record this is my trivial objtool fix.
