   This commit had some unexpected fallout.  It shouldn't be merged unless
   the following upstream commits are also merged:

   c5c69f3f0dcf9b569c8f3ad67f3af92cfcedac43
   cee6a262550f53a13acfefbc1e3e5ff35c96182c

+Subject: [PATCH] USB: dummy-hcd needs the has_tt flag
+
+commit c5c69f3f0dcf9b569c8f3ad67f3af92cfcedac43 upstream.
+
+Like with other host controllers capable of operating at both high
+speed and full speed, we need to indicate that the emulated controller
+presented by dummy-hcd has this ability.  Otherwise usbcore will not
+accept full-speed gadgets under dummy-hcd.  This patch (as1469) sets
+the appropriate has_tt flag.

+Subject: [PATCH] USB: fix regression in usbip by setting has_tt flag
+
+commit cee6a262550f53a13acfefbc1e3e5ff35c96182c upstream.
+
+This patch (as1460) fixes a regression in the usbip driver caused by
+the new check for Transaction Translators in USB-2 hubs.  The root hub
+registered by vhci_hcd needs to have the has_tt flag set, because it
+can connect to low- and full-speed devices as well as high-speed
+devices.

+Subject: [PATCH] usb: musb: core: set has_tt flag
+
+commit ec95d35a6bd0047f05fe8a21e6c52f8bb418da55 upstream.
+
+MUSB is a non-standard host implementation which
+can handle all speeds with the same core. We need
+to set has_tt flag after commit
+d199c96d41d80a567493e12b8e96ea056a1350c1 (USB: prevent
+buggy hubs from crashing the USB stack) in order for
+MUSB HCD to continue working.
