From: Sarah Sharp Date: Fri, 2 Apr 2010 22:34:10 +0000 (-0700) Subject: USB: Add stream ID field to struct urb. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=94af1220985c71cd80d6c161b7a42c51ef08b923;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git USB: Add stream ID field to struct urb. Bulk endpoint streams were added in the USB 3.0 specification. Streams allow a device driver to overload a bulk endpoint so that multiple transfers can be queued at once. Add a new field, stream_id, to struct urb so that USB 3.0 drivers can specify which stream they want the URB to be queued to.
