## Description

In the Linux kernel, the following vulnerability has been resolved:  hwmon: (corsair-cpro) Remove debugfs entries when probe fails  ccp_debugfs_init() registers debugfs files whose private data is the devm allocated ccp.  If hwmon_device_register_with_info() fails right after it, ccp_probe() returns without removing them: the HID core then frees ccp, and ccp_remove() is not called for a failed probe, so the files stay behind.  Reading one of them dereferences the freed pointer.  Remove the debugfs entries on that error path.  debugfs_remove_recursive() waits for readers already inside the show callbacks, so ccp is no longer reachable through debugfs by the time probe returns.
