Subject: The memory allocation flag GFP_KERNEL is not permissible in an
X-Git-Tag: r0_7_70~90

The memory allocation flag GFP_KERNEL is not permissible in an
interrupt callback. It has to be GFP_ATOMIC. The submit_urb
function has been called with the wrong kernel kernel flag. It's
now GFP_ATOMIC. Thanks for the feedback from Dave Brownell.
