From 1720058343fa43a1a25bfad9e62ea06e7e9743b6 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Wed, 30 Aug 2006 11:32:52 -0400 Subject: usbcore: trim down usb_bus structure As part of the ongoing program to flatten out the HCD bus-glue layer, this patch (as771b) eliminates the hcpriv, release, and kref fields from struct usb_bus. hcpriv and release were not being used for anything worthwhile, and kref has been moved into the enclosing usb_hcd structure. Along with those changes, the patch gets rid of usb_bus_get and usb_bus_put, replacing them with usb_get_hcd and usb_put_hcd. The one interesting aspect is that the dev_set_drvdata call was removed from usb_put_hcd, where it clearly doesn't belong. This means the driver private data won't get reset to NULL. It shouldn't cause any problems, since the private data is undefined when no driver is bound.
