Subject: [PATCH 0/38] treewide: add all missing put_device calls

Hi,

this is the second part of the patchset-set that aims to add missing put_device
calls when a device_register() call fails. While these issues are only
potential issues, i.e. they haven't been experienced, they are issues and
need to be fixed.

Root cause for the need for the put_device is that under a struct device lies
a kobject and under that a kref. If device_register() fails, then the kref
has already been initialized to reference count of one. This means that it
still exists and hence can cause problems if it has been kfree'd.

The patchset consists of the following patches:
