That warning should not exist in the first place, or at # least be optinal with some "-Wformat-me-harder" kind of option. # # [ Admittedly, there's also very little reason to ever* use '%hh[ud]' in # C, but what little reason there is is entirely about 'I want to see # only the low 8 bits of the argument'. So I would suggest nobody ever # use that format in the first place, but if they do, the clang # behavious is simply always wrong. Because '%hhu' takes an 'int'. It's # that simple. ] # # Reported-by: Sudip Mukherjee (Codethink) <sudipm.mukherjee@gmail.com> # Cc: Nick Desaulniers <ndesaulniers@google.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 21f9c8a13bb2a0c24d9c6b86bc0896542a28c197 # < make -s -j 32 ARCH=mips O=/kisskb/build/linus_32r6_defconfig_mips-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/mips-linux/bin/mips-linux- 32r6_defconfig ./.config.32r6_defconfig:96:warning: override: CPU_BIG_ENDIAN changes choice state .config:95:warning: override: CPU_BIG_ENDIAN changes choice state # < make -s -j 32 ARCH=mips O=/kisskb/build/linus_32r6_defconfig_mips-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/mips-linux/bin/mips-linux- help # make -s -j 32 ARCH=mips O=/kisskb/build/linus_32r6_defconfig_mips-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/mips-linux/bin/mips-linux- olddefconfig # make -s -j 32 ARCH=mips O=/kisskb/build/linus_32r6_defconfig_mips-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/mips-linux/bin/mips-linux- /kisskb/src/arch/mips/boot/dts/img/boston.dts:128.19-178.5: Warning (pci_device_reg): /pci@14000000/pci2_root@0,0,0: PCI unit address format error, expected "0,0" Completed OK # rm -rf /kisskb/build/linus_32r6_defconfig_mips-gcc11 # Build took: 0:01:21.082282
