For this also compiler shows warning.
To compile for mips I used
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=clang make.cross W=1 O=build_dir
ARCH=mips SHELL=/bin/bash drivers/iio/accel/
../drivers/iio/accel/bma400_core.c:1047:17: warning: result of comparison of
constant 18446744073709551615 with expression of type 'typeof (_Generic((msk)...
field_value = FIELD_PREP(msk, state ? 1 : 0);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../include/linux/bitfield.h:114:3: note: expanded from macro 'FIELD_PREP'
__BF_FIELD_CHECK(_mask, 0ULL, _val, "FIELD_PREP: "); \
To avoid warning can I do like this
field_value = FIELD_PREP(BMA400_INT_GEN1_MSK, state);
