## Overview

In the Linux kernel, the following vulnerability has been resolved:

bus: mhi: host: Fix controller cleanup on EDL sysfs failure

mhi_register_controller() adds the controller device before creating the
optional trigger_edl sysfs file. If sysfs_create_file() fails, the error
path only drops the device reference and leaves the device registered.

Hence, call device_del() in the error path before put_device().

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
