[PATCH v4 33/36] iio: orientation: hid-sensor-rotation: drop hid_sensor_remove_trigger() using devm API

From: Sanjay Chitroda

Date: Sun May 24 2026 - 15:34:51 EST


From: Sanjay Chitroda <sanjayembeddedse@xxxxxxxxx>

Use devm_hid_sensor_setup_trigger() to automatically release resource
during fail, unbind or removal of driver using devres framework.

This simplify the setup, remove goto, avoid manual resource cleanup in
teardown path.
