If anyone has any objections, please let me know. ------------------ From: Tomoki Sekiyama 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.
