Commit e4c7f259c5be ("USB: kaweth.c: use GFP_ATOMIC under spin_lock") makes sure that kaweth_internal_control_msg() allocates memory with GFP_ATOMIC, but kaweth_internal_control_msg() also calls usb_start_wait_urb() that still allocates memory with GFP_NOIO.
The patch fixes usb_start_wait_urb() as well. Found by Linux Driver Verification project (linuxtesting.org).
