Subject: V4L/DVB: dvb-usb: enable specifying a separate generic bulk ctrl response endpoint Author: Michael Krufky <mkru...@kernellabs.com> Date: Sun Jan 31 21:06:10 2010 -0300 Some DVB USB devices use a separate endpoint for responses to control messages sent with bulk transfers via the generic_bulk_ctrl_endpoint. When generic_bulk_ctrl_endpoint_response is set, it will be used instead of the generic_bulk_ctrl_endpoint when reading usb responses in the dvb_usb_generic_rw helper function.
