From: Alan Stern Date: Fri, 11 Oct 2013 15:29:22 +0000 (-0400) Subject: USB: add a private-data pointer to struct usb_tt X-Git-Tag: v3.13-rc1~174^2~68 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7c4bb942986fc2aa7ca4fccfed665d24525a0e21;p=kernel%2Fkernel-generic.git USB: add a private-data pointer to struct usb_tt For improved scheduling of transfers through a Transaction Translator, ehci-hcd will need to store a bunch of information associated with the FS/LS bus on the downstream side of the TT. This patch adds a pointer for such HCD-private data to the usb_tt structure.
