Since Acpi framework already exports this info to user space, Why not do this derivation in user space code ? Why do we need new ABI, if the same can be derived from existing one.
The ABI was added in the previous patch so that we can present the sensor orientation information to userspace even in the case of device tree. The purpose of this patch is to provide a consistent ABI to userspace, i.e. to avoid doing one thing in the ACPI case and another thing in the case of device tree.
