[PATCH 0/2] driver core: remove software node from platform devices on device release

This fixes an issue in platform device code where, if we specify a
software node for a platform device using struct platform_device_info,
it will not be removed on device .release().

The second patch adds a test-case that can be used to reproduce the
problem and prove that the fix works.

First patch should go into v7.1 while patch 2/2 can be queued for v7.2.
