AVStream calls a minidriver's AVStrMiniDeviceSetPower routine when it receives an IRP_MN_SET_POWER.
Device [in]Pointer to the KSDEVICE structure that received the IRP_MN_SET_POWER.
Irp [in]The IRP_MN_SET_POWER issued by Device.
To [in]The target device power state.
From [in]The current device power state.
If a driver has registered its device for idle detection, the power manager sends an IRP_MN_SET_POWER to change the power state of an idle device.
The minidriver specifies this routine's address in the SetPower member of its KSDEVICE_DISPATCH structure.
This routine is optional.
