dell-wmi-sysman: New possibility to set BIOS values for Dell systems has some bugs

[Alexander Naumann <alexandernaumann@xxxxxx>]

I have seen this new option and wanted to test it on an R240 (OEM device).

But it is not working.


I did compile this as a module and it was loading fine. But actually it
is not.

This function call here returns 0:

ret = init_bios_attr_set_interface();


But "wmi_priv.bios_attr_wdev" is not set!

So loading the module is returning with exit code 0 (what is wrong!).
Variable "ret" should be set to 1 in this case


Also unloading the module will crash (I guess because the sys entries do
not exists).

I can send you an crashdump later on.


Any ideas why it is not working at all?
