Can you report this issue upstream? Gues to reach out are according to
get_maintainers.pl script:

Lorenzo Bianconi <lorenzo@kernel.org> (maintainer:ST LSM6DSx IMU IIO DRIVER)
Jonathan Cameron <jic23@kernel.org> (maintainer:IIO SUBSYSTEM AND DRIVERS)
Lars-Peter Clausen <lars@metafoo.de> (reviewer:IIO SUBSYSTEM AND DRIVERS)
linux-iio@vger.kernel.org (open list:ST LSM6DSx IMU IIO DRIVER)
linux-kernel@vger.kernel.org (open list)

Please keep us in the loop.

Regards,
Salvatore
