This patch fixes it. # # Note that hex_to_bin returns -1 on error and hex2bin return -EINVAL on # error - so we can't just return the variable "hi" or "lo" on error. # This inconsistency may be fixed in the next merge window, but for the # purpose of fixing this bug, we just preserve the existing behavior and # return -1 and -EINVAL. # # Signed-off-by: Mikulas Patocka # Reviewed-by: Andy Shevchenko # Fixes: b78049831ffe ("lib: add error checking to hex2bin") # Cc: stable@vger.kernel.org # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 e4d8a29997731b3bb14059024b24df9f784288d0 # < make -s -j 32 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # Added to kconfig CONFIG_TRIM_UNUSED_KSYMS=n # Added to kconfig CONFIG_UBSAN=n # < make -s -j 32 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 32 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4913:warning: override: reassigning to symbol PPC64 .config:4916:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD .config:4918:warning: override: reassigning to symbol GCC_PLUGINS # make -s -j 32 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/dc_fpu.c: In function 'dc_fpu_begin': /kisskb/src/drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/dc_fpu.c:97:25: error: implicit declaration of function 'enable_kernel_altivec'; did you mean 'enable_kernel_vsx'?
