this seems to be misnamed. per the wmi naming convention _params are structs
passed from firmware. you cannot pass a pointer to an array from firmware to
host, you can only pass the array contents. hence seems this is a host-only
struct and should be named _arg

again seems this should be _arg

same here

reminder from the top of the file:
/* Naming conventions for structures:
 *
 * _cmd means that this is a firmware command sent from host to firmware.
 *
 * _event means that this is a firmware event sent from firmware to host
 *
 * _params is a structure which is embedded either into _cmd or _event (or
 * both), it is not sent individually.
 *
 * _arg is used inside the host, the firmware does not see that at all.
