This is a note to let you know that I've just added the patch titled
usb: cdns3: trace: using correct dir value
to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch.
The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.
If you have any questions about this process, please let me know.

It should use the correct direction value from register, not depends on previous software setting. It fixed the EP number wrong issue at trace when the TRBERR interrupt occurs for EP0IN.
When the EP0IN IOC has finished, software prepares the setup packet request, the expected direction is OUT, but at that time, the TRBERR for EP0IN may occur since it is DMULT mode, the DMA does not stop until TRBERR has met.
