probe in usb don't need to be atomic. So GFP_KERNEL can be used here,
instead of GFP_ATOMIC.

Hello for me it was simple and obvious patch.
Is there something wrong about it?

It has been only 4 days.  For a non-bugfix and for something that is
only a "cleanup" change, give it at least 2 weeks please.

Relax, there is no rush for stuff like this.

thanks,
