It does? Where?
usb_create_hcd() ...... dev_set_drvdata(dev, hcd); ......
In fact, should be dev->p->driver_data, accurately speaking.
Well, usbcore does not use this value.
It seems it does use it still, in usb_hcd_platform_shutdown() -- at least for the platform drivers that choose to call this function (but MUSB is not amongst them)...
It's just the default; drivers can change it if they want. usbcore does not _insist_ on the value.
Yeah, looks like this...
