Subject: [PATCH 0/6] Preparations for fixing WMI reprobing issue

This patch series contains preparations for fixing the WMI reprobing
issue discussed here:

https://lkml.kernel.org/1252c8fb-8d5f-98ad-b24a-5fabec2e1c8b@gmx.de

It mainly aims to decouple some parts of the WMI subsystem from the
wmi_block_list, which is going to get replaced in the future. It also
fixes some issues, like a probe failure when failing to register WMI
devices and a potential issue when opening the wmi char device.

The changes where tested on a Dell Inspiron 3505 and appear to work,
but additional feedback especially on the third patch is appreciated.
