Subject[PATCH v3] AMD_SFH: Fix for incorrect Sensor index
Date
From: Sandeep Singh <sandeep.singh@amd.com>

It appears like the accelerometer/magnetometer and gyroscope
indices were interchanged in the patch series which got into
for-5.11/amd-sfh-hid until Mandoli/Richard reported to us.
Ideally sensor indices should be 0,1,2 for the accelerometer,
Gyroscope, Magnetometer respectively, but this interchanged
possibly could be because i was using a test MP2 firmware
on my machine.

This patch fixes the earlier commit with the right sensor
indices and also removing unused structures
_hid_report_descriptor,
_hid_device_descriptor as reported by Richard.
