[ 18/62] USB: yurex: Fix missing URB_NO_TRANSFER_DMA_MAP flag in urb

From: Greg KH
Date: Tue Apr 24 2012 - 18:34:49 EST


3.3-stable review patch. If anyone has any objections, please let me know.

------------------

From: Tomoki Sekiyama <tomoki.sekiyama@xxxxxxxxx>

commit 532f17b5d59bf0deb6f1ff9bc1fb27d5b5011c09 upstream.

Current probing code is setting URB_NO_TRANSFER_DMA_MAP flag into a wrong urb
structure, and this causes BUG_ON with some USB host implementations.
This patch fixes the issue.
