Subject: [PATCH 5.15 07/20] objtool: Add a missing comma to avoid string concatenation
Date: Tue, 24 Jan 2023 10:50:57 -0800	[thread overview]
Message-ID: <20230124185110.143857-8-ebiggers@kernel.org> (raw)
In-Reply-To: <20230124185110.143857-1-ebiggers@kernel.org>

From: "Eric W. Biederman" <ebiederm@xmission.com>

commit 1fb466dff904e4a72282af336f2c355f011eec61 upstream.

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.
