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/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 e4d8a29997731b3bb14059024b24df9f784288d0 # < make -s -j 24 ARCH=s390 O=/kisskb/build/linus_s390-allnoconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- allnoconfig # < make -s -j 24 ARCH=s390 O=/kisskb/build/linus_s390-allnoconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- help # make -s -j 24 ARCH=s390 O=/kisskb/build/linus_s390-allnoconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- olddefconfig # make -s -j 24 ARCH=s390 O=/kisskb/build/linus_s390-allnoconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- Completed OK # rm -rf /kisskb/build/linus_s390-allnoconfig_s390x-gcc11 # Build took: 0:00:39.174390
