  "message": "USB: fix the clear_tt_buffer interface\n\nThis patch (as1255) updates the interface for calling\nusb_hub_clear_tt_buffer().  Even the name of the function is changed!\n\nWhen an async URB (i.e., Control or Bulk) going through a high-speed\nhub to a non-high-speed device is cancelled or fails, the hub\u0027s\nTransaction Translator buffer may be left busy still trying to\ncomplete the transaction.  The buffer has to be cleared; that\u0027s what\nusb_hub_clear_tt_buffer() does.\n\nIt isn\u0027t safe to send any more URBs to the same endpoint until the TT\nbuffer is fully clear.  Therefore the HCD needs to be told when the\nClear-TT-Buffer request has finished.  This patch adds a callback\nmethod to struct hc_driver for that purpose, and makes the hub driver\ninvoke the callback at the proper time.\n\nThe patch also changes a couple of names; \"hub_tt_kevent\" and\n\"tt.kevent\" now look rather antiquated.\n\nSigned-off-by: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nCc: stable \u003cstable@kernel.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n",
