BMI088 driver was failing to build for Kernel version > 6.2 and the following error is seen: drivers/bmi088/bmi088_core.c:1043:42: error: 'struct iio_dev' has no member named 'mlock' mutex_lock(&st->snsrs[hw].bmi_iio->mlock); mlock field is moved from indio_dev to iio_dev_opaque structure from v6.2 onwards. Instead of using kernel version, use conftest.sh script which checks for the 'mlock' field in iio_dev_opaque structure or not.
