Subject: mainline build failure for arm64 allmodconfig with clang
Date: Thu, 11 Aug 2022 08:36:24 +0100 [thread overview]
Message-ID: <YvSxeDkmwxcJL+Z0@debian> (raw)
Hi All,
The latest mainline kernel branch fails to build for arm64 allmodconfig
with clang. The errors are:
sound/soc/sof/ipc3-topology.c:2343:4: error: format specifies type 'unsigned char' but the argument has type 'int' [-Werror,-Wformat]
SOF_ABI_MAJOR, SOF_ABI_MINOR, SOF_ABI_PATCH);

For both, git bisect points to 0af5cb349a2c ("Merge tag 'kbuild-v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild")
The last good build for arm64 clang was with e394ff83bbca ("Merge tag 'nfsd-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux")
I will be happy to test any patch or provide any extra log if needed.
