I am having trouble reproducing this build error on both jic23-iio/togreg and
linus/master v6.11.rc7 on an aarch64 box with the same compiler version.
Maybe a config option is causing this?
However, I will add #include <linux/bitfield.h> to remedy this issue if
some edge case is being hit.
Best regards,
Alex
