Hi,
please do this DMI check during module initialization. This avoids having an
useless WMI driver
on unsupported machines and allows for marking tested_devices_dmi_table as
__initconst.
I wonder how to do it since I don't use module_init manually but
module_wmi_driver to register the module.
Besides that, maybe a "force" module parameter for overriding the DMI
checking could be
useful?
Considering the bricking potential i somewhat want for people to look in the
source first, so i would not implementen a force module parameter.
Kind regards,
Werner
