FIELD_GET require mask field to be constant, however it is wrapped by a
function which will cause error
././include/linux/compiler_types.h:320:38: error: call to ‘__compiletime_assert_270’ declared with attribute error: FIELD_GET: mask is
not constant
320 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)
redefine cal_read_field as a macro
