Subject: USB: yurex: Fix missing URB_NO_TRANSFER_DMA_MAP flag in urb
From: Tomoki Sekiyama <[email protected]>
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.
