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, a Lenovo E51-80,
a Acer Aspire E1-731 and a Asus PRIME B650-Plus motherboard and appear
to work, but additional feedback especially on the third patch
is appreciated.

Changes since v2:
- Drop already merged first patch
- break the paragraphs of the second patch with an empty line
