The remote wake-up function is a regular function on usb hid device

more convenient. This patch is to enable remote wakeup function for
usb hid device.

Hi,

I am afraid we cannot do this. It will cause regression.
Consider for example the case of laptops with touchscreens
that will trigger a wake up when the laptop is closed.

Hi oliver,


system ask that must it must be accped a acpi lid open event then system will always into resume state for laptop, otherwise, eventhough that system be wakeuped by other event then system will continue into suspend.

and for laptop usb wakeup that as general ask bios to enable usb wakeup then if need do more things to enable usb wakeup I think this usb wakeup function isn't friendly and inconveient, so enable it by default.
after add this patch, if want to use usb wakeup function it only need enable bios configure it think it is appropriate.

BRs,
Yinbo.
