[PATCH] remoteproc: qcom_wcnss_iris: Add missing put_device() on error in probe
From: Dan Carpenter
Date: Wed Apr 02 2025 - 07:00:10 EST
The device_del() call matches with the device_add() but we also need
to call put_device() to trigger the qcom_iris_release().
Fixes: 1fcef985c8bd ("remoteproc: qcom: wcnss: Fix race with iris probe")

This patch is based on static analysis and has not been tested. Please
review carefully, etc. Another option would be to call device_unregister()
