Subject: [PATCH 0/3] imu: st_lsm6dsx: Add support for rotation sensor

This series adds support for the rotation sensor functionality present in
some chips from the ST LSM6DSX IMU family.
The first commit is a fix to a previous commit of mine [1] which made it to
6.19-rcX; the fix technically changes userspace, but this should be OK as
long as it goes in during this release cycle.
Tested on LSM6DSV16X.
