usb: gadget: f_hid: eliminate abuse of ep->driver data
Since ep->driver_data is not used for endpoint claiming, neither for enabled/disabled state storing, we can reduce number of places where we read or modify it's value, as now it has no particular meaning for function or framework logic. In case of f_hid we only need to store in ep->driver_data pointer to struct f_hidg, as it's used in f_hidg_req_complete() callback. All other uses of ep->driver_data are now meaningless and can be safely removed. Signed-off-by: Robert Baldyga <r.baldyga@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
